Executive Summary:

  • Islamic State (IS) militants conducted a well-planned strike in Oman on a Shi’ite mosque on July 15, 2024. While early reports focused on the attack’s potential goal of inciting sectarian violence, it is more likely to have been meant as a warning to Muscat to cease diplomatic activities involving regional governments, Shi’ite groups, and/or the West.
  • Oman’s peace with regard to jihadism is deep-rooted in local Ibadi Muslim traditions. Muscat’s tolerance has enabled it to serve as a diplomatic hub, facilitating negotiations between the United States and Iran as well as Saudi Arabia and the Houthi rebels in Yemen.

Islamic State (IS) militants struck a Shi’ite mosque in Oman on July 15, 2024, scything down dozens of worshipers while hundreds of others stampeded in a desperate effort to evade an unexpected hail of bullets (see Terrorism Monitor, August 21, 2024). The attack on Muscat’s ‘Ali bin Abi Talib mosque puzzled many observers of the Middle East, as sectarian violence is nearly unknown in Oman, where most citizens, rather than being Sunni or Shi’ite, follow the relatively little-known and non-aggressive Ibadi school of Islam.

The Shi’ite mosque, on the fringe of Muscat, the Omani capital, has a mainly Pakistani congregation. Oman is a nation of four million people, of whom 40 percent are expatriate workers, mostly from South Asia. Though 400,000 of these are Pakistanis, Pakistan’s ambassador to Oman declared the attack was not “a Pakistan-targeted operation” (Times of Oman, July 17, 2024).

When the shooting began in the evening, nearly 500 people were assembled in the courtyard. Most worshipers were able to rush inside the mosque before a policeman gave his life closing the doors. Five other people were killed, including four Pakistanis and one Indian national. At least three of the dead died trying to shield children from the gunfire with their bodies (The National [Abu Dhabi], July 23, 2024). Some 30 were wounded, including emergency services personnel (Muscat Daily, July 16, 2024).

Many survivors credited the action of the Royal Oman Police in preventing a massacre: “If not for the counter-firing by security officials stationed around the mosque, the tragedy would have been unimaginable” (Times of Oman, July 16, 2024). Most of the mosque attendees had been rescued by 2:15 AM, but a firefight between the attackers and security services continued well into the morning.

IS timed the attack to occur on Ashura, the Shi’ite day of mourning for Husayn bin ‘Ali. He was the grandson of Muhammad who refused to recognize the Umayyad succession to the Caliphate in the seventh century and was consequently killed at the Battle of Karbala. Hatred of the Shi’a was likely only a means of inciting the attackers as a geopolitical strategy was unlikely to inspire the kind of fanaticism necessary to slaughter innocents. The timing of the attack thus inflicted religious insult while provoking a maximum emotional impact on the targeted worshipers.

Islamic State’s Attackers in Oman

On July 18, 2024, IS released a three-minute video through its Amaq news agency of the three self-styled “soldiers of the Islamic State” who carried out the attack. The three native Omani brothers were, according to the Royal Oman Police, “influenced by others and had misguided ideas” (Times of Oman, July 18, 2024; Al-Watan [Muscat], July 18, 2024). The brothers are likely to have had ties to the Islamic State in Yemen Province (ISYP), whose homeland in Yemen borders Oman.

The video was filmed outdoors in front of an apparently homemade, spray-painted IS black flag. After calling on young Arab Muslims to combat “apostates” and “tyrants,” the speaker declared their attack would avenge both Sunni jihadists held in various Shi’a prisons and the reputation of Aisha, who is “the mother of believers” and the Prophet Muhammad’s third wife. [1] 

The Omani perpetrators, who were likely Salafist Sunnis, made reference to Ibadism as a sectarian form of Islam in their video. Sunni militants condemn the Shi’a as rawafidh (“rejectionists,” i.e., of the first three caliphs, the successors of Muhammad). Most of the Sunni Muslims of southern Oman belong to the moderate Shafi’i madhab (school of Islamic jurisprudence), considered to be relatively infertile ground for religious extremism. Aside from their evident loathing for Oman’s long-accepted Shi’ite community, the attackers have thus also demonstrated an intolerance uncommon to Oman’s dominant Sunni faith.

Given the bloodshed in Gaza, the gunmen further explained that jihad did not need to only target Jews on behalf of “Palestine,” but must also strike at “polytheists” (a derogatory Salafist term for Shi’ites). The video concluded with the militants pledging allegiance to Abu Hafs al-Hashimi al-Qurashi, the fifth caliph (since August 2023) of IS’s so-called Islamic caliphate.

The attack showed a significant degree of planning, with the assailants taking positions behind floodlights on the roof of a neighboring building. This provided a full view of their targets while preventing a precise location of their shifting positions. Chanting “You non-believers, this is your end,” they engaged Omani police and soldiers for ten hours before their deaths (The National [Abu Dhabi], July 17, 2024).

Background to Tolerance

The empire-building Portuguese arrived in Oman in 1507, unleashing seamen recruited from the prisons of Lisbon on Muscat and other ports. Using extreme brutality to make up for inferior numbers, the Portuguese burned the mosques and mutilated or killed those Arabs who resisted. [2] However, under nearly 150 years of Portuguese rule, Oman became a regional trading center, attracting migration from India, Iran, and other points. In this way, Oman emerged as a multi-faith, multi-ethnic, and multi-cultural bastion once the despised Portuguese were run out by the Ibadi Imams with Dutch and British naval assistance.

Oman’s commanding position on the Strait of Hormuz, the Gulf of Oman, and the Arabian Sea, with the latter’s connections to the Indian Ocean, has provided historical ties through seafaring traders and merchants to many parts of Asia, east Africa, and the Middle East. The result is that, despite its isolationist reputation, Oman is home to a variety of languages, ethnicities, and faiths, including Islam and Hinduism. Oman’s majority Muslim population is roughly split between Ibadis and Sunnis, with the Shi’a forming a smaller community representing some 5 percent of the population.

This exposure to other cultures and intellectual trends, combined with the moderate nature of Ibadi Islam, created in Oman a tolerant and diverse society that has largely escaped the religious and ethnic fissures that have so troubled its neighbors in recent decades.

Who Are the Ibadis?

The Ibadis are believed to be an offshoot of the early Islamic Kharijite movement, which fought a long war against Muslim rulers they accused of violating Islamic law. A focus on asceticism and egalitarianism brought many followers to the Kharijite ranks from the nomadic Bedouin and the mawali, who are non-Arab converts to Islam (including many Berbers). In 692, ‘Abd Allah bin Ibad created a more moderate but socially conservative breakaway version of the inflexible Khawarij movement that was prepared to live in harmony with other Muslims. This movement came to be known as Ibadism after its founder.

Oman’s Ibadi Muslims generally do not pursue the spread of their madhab. For example, during the long period of direct Omani rule over Zanzibar (1698–1861), little if any effort was made to convert East Africans to Ibadi Islam. [3] Ibadis do not seek the establishment of a global caliphate nor the territorial expansion of Islam.

Outside of Oman, Ibadis are found in smaller numbers in the Tunisian island of Djerba, in the Berber community of Libya’s Nafusa Mountains, and in the Berber Mzab Valley region of Algeria, where the Ibadis played a major role in facilitating the trans-Saharan African slave trade. The Omanis also had a long presence in Zanzibar and East Africa as merchants and slave traders, creating over the years a new class of Afro–Omanis whose most prominent member was the slaver and explorer Tippu Tib (1837–1905).

The Omani Reaction

Expressing his shock that Omanis carried out the attack in IS’s name, Oman’s Grand Mufti, Sheikh Ahmad bin Hamad al-Khalili, insisted that: “The norm in this good country is that Omani education rejects, by nature, any aggression against a citizen or expatriate due to an intellectual or sectarian disagreement” (IQNA [Tehran], July 19, 2024).

In contrast, one leading Omani commentator suggested responsibility for the attack lay with the United States, claiming that IS was created and directed in Washington, D.C. (Oman Daily, July 21). [4] Suspicion of American and Israeli direction of IS is common in the Middle East, especially due to IS’s focus on attacking fellow Muslims and its reluctance or inability to target Israel or Israeli interests. In Oman, a familiar but bitter joke made the rounds after the mosque massacre: Q. “When will Islamic State attack the Israelis?” A. “As soon as they convert to Islam.”

Another Omani commentator warned of the complacency created by popular belief in an “imagined Omani… tolerant, peaceful, innocent, a silent citizen…” a vision that ignores Omani society’s “many molds related to religious and political beliefs, ideas, and visions” (Oman Daily, July 22, 2024). Others, meanwhile, questioned why individuals “who have received qualitative education, hold high-level academic degrees from prestigious universities and hold lucrative jobs slip into such dangerous pitfalls” (Oman Daily, July 21, 2024). Only a handful of Omanis are known to have participated in jihadist movements since the 1990s.

The Jihadist Response

An editorial published in IS’s official magazine al-Naba condemned Oman for its good relations with Iran and called for the states of the Arabian Peninsula to expel all Shi’a to end their “cancerous infiltration.” The editorial further accused Oman’s “apostate” government of “throwing open the doors” of Oman to the Shi’a, despite their centuries-long presence there. [5] Al-Naba further accused Oman’s government of creating, through toleration, an equivalency between Sunnis and Ibadis as well as Shi’a and pagans.

Abu Muhammad al-Maqdisi

Jordanian Salafist Abu Muhammad al-Maqdisi, a leading jihadist theorist, unfavorably contrasted the IS’s attack on a “remote and marginal” Shi’a mosque in Oman with the successful and strategic efforts of Shi’a groups like Hezbollah and the Yemen-based Houthis against the “Jews and Crusaders.” He mentioned the July 19, 2024, Houthi drone attack on Tel Aviv, in particular. According to al-Maqdisi, “only a mentally ill person” would prioritize attacks on Shi’a non-combatants over strikes on Jews and Christians. [6] 

Conclusion 

To understand the attack on the ‘Ali bin Abi Talib mosque in Muscat, it is necessary to recognize what caused this IS cell to be activated at this time. Though it is entirely possible for cells, like lone wolf terrorists, to self-activate, it seems unlikely in this case. The Middle East (and even Oman) abounds with more valuable targets than an obscure mosque frequented by Pakistani expats. The slaughter of a handful of worshippers by a dedicated team of jihadists willing to give their lives will not drive the Shi’a from Oman, nor is it likely to encourage other Omanis to take up the cause of IS. Hatred of the Shi’a was likely only a means of inciting the attackers, as geopolitical strategy was unlikely to inspire the kind of fanaticism necessary to slaughter innocents.

Though Oman has been described as a mediator in Middle East conflicts, its role is better described as facilitation, offering a discrete venue for antagonists to pass messages or engage in direct talks without Omani involvement. Conducted out of sight of the media, these back-channel negotiations often yield positive results.

Despite pressure from its Sunni neighbors in the Arabian Peninsula, Oman has maintained good relations with Shi’ite Iran and acted as a facilitator in Iranian contacts with Saudi Arabia and the United States. On May 19, 2024, the Iranian mission to the UN confirmed that Oman was hosting ongoing indirect talks between the United States and Iran (Iran International, May 19, 2024). Oman has similarly facilitated talks between the Iran-backed Houthi movement and its Saudi antagonists (Al Jazeera, July 24). On July 19, 2024, IS condemned all these communications, claiming the “infidel” powers were encouraged by Oman to unite in a war against it. [7] 

If IS wished to warn off Oman from further facilitation of negotiations benefitting Shi’ite Iran and the Zaydi Shi’ite Houthi movement, the apparently pointless targeting of a Shi’a mosque in Muscat begins to make sense. Rather than being an attempt to sow sectarian discord, the attack on the ‘Ali bin Abi Talib mosque can more reasonably be interpreted as a warning to Oman to cease diplomatic activities involving Iran and its so-called proxies.

Notes:

The daughter of Abu Bakr, first of the Rashidun (rightly guided) caliphs (the first four successors of Muhammad), she gained the eternal ire of the Shi’a for opposing the succession of ‘Ali, the last of the Rashidun and the first Imam of the Shi’a. In Shi’a discourse, she is condemned for her political involvement as a female and her alleged dislike of the Ahl al-Bayt (family of the Prophet).

I do… No, it’s no mistake” (hughhewitt.com, August 12, 2016).

Credibility of Russia’s Red Sea Naval Facility Agreement with Sudan

Eurasia Daily Monitor Vol. 22, Jamestown Foundation, Washington DC

Andrew McGregor

March 6, 2025

Executive Summary:

  • Moscow is pursuing the construction of a naval port on Sudan’s Red Sea coast, reflected in the finalization of an agreement between Russia and Sudan in February.
  • The deal appears to be part of the Kremlin’s efforts to create new strategic assets in Africa following the loss of air and naval bases in Syria.
  • The elected government of Sudan’s inability to ratify the agreement reflects the salience of domestic and international opposition to a changed security situation on this vital maritime trade route.

Russia and the leading faction in Sudan’s ongoing civil war have reportedly finalized an agreement to establish a Russian naval base on the Red Sea coast. Since the opening of the Suez Canal in 1869, there may be no more strategically important body of water in the world than the Red Sea. Access to the sea, which carries 10 to 12 percent of global trade on its waters, is gained only through the Egyptian-controlled canal to the north and the narrow Bab al-Mandab strait to the south (The Observatory of Economic Complexity, accessed March 4). So far, no state outside of the region has established a naval base between the canal and Bab al-Mandab since the departure of the British from Sudan’s primary Red Sea port, Port Sudan, in 1956. That appeared to change on February 12 with the announcement that an agreement had been reached to construct a Russian naval base in Port Sudan.

The announcement was made by Dr. ‘Ali Yusuf Sharif, appointed in November 2024 as nominal foreign minister by Lieutenant General ‘Abd al-Fatah al-Burhan, whose faction controls most of Sudan. During a televised press conference in Moscow with his Russian counterpart, Sergey Lavrov, Sharif said “This is an easy question, there are no obstacles, we are in complete agreement” (Izvestiya, February 12; Al Arabiya; Atalayar, February 13). After the meeting, Lavrov expressed his appreciation for the “balanced and constructive position” taken by Sudan on the situation in Ukraine (TASS, February 12). There has been no confirmation from Moscow of the official signing of this deal.

‘Ali Yusuf Sharif and Sergei Lavrov

Since 2017, Moscow and Khartoum, represented by the since-deposed Sudanese president, ‘Omar al-Bashir, have discussed the creation of a Russian naval base in Sudan (See EDM, December 6, 2017). A preliminary agreement, forming the basis for the current pact, was developed in 2020 but never implemented. This original agreement includes a 25-year lease with a possible ten-year extension (Uz Daily, November 15, 2020).

Moscow holds a vested interest in establishing a naval base in this region, especially as the future of its naval base in Tartus, Syria remains uncertain (Military Review, December 11, 2024; Izvestiya, January 22). The primary function of Russia’s new “logistical base,” as it is described by Moscow, is to repair and replenish up to four Russian naval craft at a time, including nuclear-powered vessels. The base will house up to 300 personnel, with an option to increase this number with Sudan’s permission (TASS, February 12; Sudan Tribune, February 12). Russia will be responsible for air defense and internal security, while Sudan will provide external security in tandem with temporary Russian defensive positions outside the base. Russia will be at liberty to import and export weapons, munitions, and military material to and from the base (Vreme, February 13).

The completion of the deal may open the possibility for Sudan to purchase Russian-built SU-30 and SU-35 fighter jets, which it has sought since 2017 (Sudan Tribune, July 16, 2024). The sale has been complicated by an inability to finalize the port offer, U.S. sanctions on Russian manufacturers, and Sudan’s difficulty in making payments. Oil-rich Algeria, by comparison, has just completed a deal to obtain 14 fifth-generation Russian SU-57 stealth fighters (Janes.com, February 14).

Cooperation with Russia is also attractive to Sudan given Khartoum’s need to secure oil exports on its coast. Port Sudan serves as the export point for Sudan’s troubled oil industry, now operating at only slightly more than 40 percent of pre-war production. Sudan’s Ministry of Energy and Petroleum (MOP) is currently discussing a new partnership with Russia related to exploration, financing, and technical assistance (Sudan Tribune, January 25). In November 2024, MOP Minister Dr. Muhyaddin Na’im Muhammad Sa’id met with his Russian counterpart in Moscow to discuss prospects for joint projects and attractive areas for Russian companies to invest in oil and gas exploration (Sudan News Agency, November 16, 2024). The People’s Republic of China (PRC) was formerly Sudan’s main energy partner. According to one Sudanese economic expert, “the [civil] war has changed this equation” in favor of gaining expertise, especially related to oil extraction, from Russia (Sudan Tribune, January 25).

For Russia, there is a risk in initiating the construction of an expensive naval facility during a period of continued instability in Sudan. There is also the question of overland supply from Khartoum to Port Sudan, which essentially follows a single highway that has been blocked in the past by Beja protestors (New Arab, October 27, 2021; see EDM, November 14, 2023). To mitigate such risks, Sudan appears to be trying to follow the “Djibouti approach” to hosting foreign military bases. Djibouti currently hosts separate French, Chinese, U.S., Italian, and Japanese military facilities while U.K. forces are hosted at the U.S. facility (see EDM, July 8, 2024). According to Sharif, the new Russian base in Sudan, like those in Djibouti, will not pose a threat to the sovereignty of its neighbors nor Sudan itself (Anadolu Ajansi, February 13).

There are, however, major and ongoing differences between the military and civil components of the de facto government in Port Sudan that could sideline Russian ambitions in the Red Sea. Sharif’s claim that there were “no obstacles” to implementing the agreement is not necessarily correct. There is broad opposition to the unelected leaders of the Transitional Sovereignty Council (TSC) and Sudanese Armed Forces (SAF) making a deal with major implications for Sudanese sovereignty (see Terrorism Monitor, April 28, 2023). As the deal cannot presently be ratified by any elected body in Sudan, there is a strong possibility that a future government (elected or otherwise) might reject the deal entirely as having no legal legitimacy. The January 20 cancellation of Russia’s 2017 49-year lease on the port of Tartus by the new Syrian regime provides an exemplary lesson on such a danger (Maritime Executive, January 21).

Another approach the Sudanese leadership may use to mitigate security risks, and in turn, may increase Russia’s attraction to creating a naval base in the country, is via deliberate changes in government representation. The de facto leader of Sudan is Lieutenant General ‘Abd al-Fatah al-Burhan, chair of the unelected Transitional Sovereignty Council and commander-in-chief of the Sudanese Armed Forces. Al-Burhan’s government is now located in Port Sudan rather than war-torn Khartoum. Al-Burhan differs from previous leaders, as he has attempted to garner support from eastern Sudan, a traditionally impoverished area with little influence or representation in the central government. Most of the rebellions, coups, and civil conflicts that have plagued Sudan since independence and effectively prevented its successful development have been sparked by the inequality, domination, and monopolization of power. Since eastern Sudan has been dominated since independence by the Arab Nubian elites of northern and central Sudan, al-Burhan’s emphasis on involving eastern Sudan in his government represents a measure to prevent future coups or conflict. One of the figures who will likely be involved in establishing a Russian naval base in Sudan is ‘Umar Banfir, the new trade minister. Banfir is the former director of Sudan’s Sea Ports Authority and is expected to represent eastern interests to the government (Jordan Times, November 4, 2024).

Sanctions imposed by the United States on the SAF and al-Burhan personally in the last days of the Biden Administration appear correlated with al-Burhan’s renewed interest in securing the naval base deal with Russia (US Treasury Department, October 24, 2024; US Department of State, January 16; US Treasury Department, January 25).

Meanwhile, there is little evidence to suggest that the new Trump administration will impose additional sanctions or attempt to restrict Sudan’s pursuit of a new deal with Russia given the previous removal of sanctions under the first Trump administration (Congressional Research Service, July 5, 2017). Nearby Egypt and Saudi Arabia remain firmly opposed to the deal (Sudan Tribune, July 16, 2024).

Domestic political opposition, foreign objections, tribal unrest, and local fears that a Russian base might attract attacks from rivals, which in turn could damage or shut down Sudan’s most important port, remain considerable threats to the construction of a Russian naval facility in Port Sudan. These considerations also threaten Russian attempts to reinvigorate Sudan’s oil production, which has been declining for years due to a lack of investment and civil conflict. While the Russian naval base deal in Sudan holds strategic potential for Moscow, its success hinges on overcoming these political, domestic, and regional challenges.
