ISIS affiliate linked to Moscow attack has global ambitions

WASHINGTON — Five years ago this month, a US-backed Kurdish and Arab militia ousted Islamic State group fighters from a village in eastern Syria, the group’s last sliver of territory.

Since then, the organization that once staked out a self-proclaimed caliphate across Iraq and Syria has metastasized into a more traditional terrorist group — a clandestine network of cells from West Africa to Southeast Asia engaged in guerrilla attacks, bombings and targeted assassinations.

None of the group’s affiliates have been as relentless as the Islamic State in Khorasan, which is the Islamic State group’s Afghanistan affiliate; is also active in Pakistan and Iran; and has set its sights on attacking Europe and beyond. US officials say the group carried out the attack near Moscow on Friday, killing scores of people and wounding many others.

In January, Islamic StateKhorasan, or ISIS-K, carried out twin bombings in Iran that killed scores and wounded hundreds of others at a memorial service for Iran’s former top general, Qassem Soleimani, who was targeted in a US drone strike four years earlier.

“The threat from ISIS,” Avril Haines, director of national intelligence, told a Senate panel this month, “remains a significant counterterrorism concern.” Most attacks “globally taken on by ISIS have actually occurred by parts of ISIS that are outside of Afghanistan,” she said. Gen. Michael Kurilla, head of the military’s Central Command, told a House committee on Thursday that ISIS-K “retains the capability and the will to attack US and Western interests abroad in as little as six months with little to no warning.”

US counterterrorism specialists Sunday dismissed Russia’s suggestion that Ukraine was behind Friday’s attack near Moscow. “The modus operandi was classic ISIS,” said Bruce Hoffman, a terrorism scholar at the Council on Foreign Relations.

The assault was the third concert venue in the Northern Hemisphere that the Islamic State group has struck in the past decade, Mr. Hoffman said, after an attack on the Bataclan theater in Paris in November 2015 (as part of a broader operation that struck other targets in the city) and a suicide bombing at an Ariana Grande concert in Manchester Arena, England, in May 2017.

The Islamic State-Khorasan (ISIS-K), founded in 2015 by disaffected members of the Pakistani Taliban, burst onto the international jihadi scene after the Taliban toppled the Afghan government in 2021. During the US military withdrawal from the country, ISIS-K carried out a suicide bombing at the international airport in Kabul in August 2021 that killed 13 US service members and as many as 170 civilians.

Since then, the Taliban have been fighting ISIS-K in Afghanistan. So far, the Taliban’s security services have prevented the group from seizing territory or recruiting large numbers of former Taliban fighters, according to US counterterrorism officials.

But the upward arc and scope of ISIS-K’s attacks have increased in recent years, with cross-border strikes into Pakistan and a growing number of plots in Europe. Most of those European plots were thwarted, prompting Western intelligence assessments that the group might have reached the lethal limits of its capabilities.

In July, Germany and the Netherlands coordinated arrests targeting seven Tajik, Turkmen and Kyrgyz individuals linked to a ISIS-K network who were suspected of plotting attacks in Germany.

Three men were arrested in the German state of North Rhine-Westphalia over alleged plans to attack the Cologne Cathedral on New Year’s Eve. The raids were linked to three other arrests in Austria and one in Germany on Dec. 24. The four people were reportedly acting in support of ISIS-K. US and other Western counterterrorism officials say these plots were organized by low-level, amateurish operatives who were detected and thwarted relatively quickly.

“Thus far, ISIS-Khorasan has relied primarily on inexperienced operatives in Europe to try to advance attacks in its name,” Christine Abizaid, head of the National Counterterrorism Center, told a House committee in November.

But there are worrisome signs that Islamic State-Khorasan

or ISIS-K is learning from its mistakes. In January, masked assailants attacked a Roman Catholic church in Istanbul, killing one person. Shortly afterward, the Islamic State group, through its official Amaq News Agency, claimed responsibility. Turkish law enforcement forces detained 47 people, most of them Central Asian nationals.

Since then, Turkish security forces have launched mass counteroperations against Islamic State group suspects in Turkey, Syria and Iraq. Several European investigations shed light on the global and interconnected nature of Islamic State group finances, according to a United Nations report in January, which identified Turkey as a logistical hub for Islamic StateKhorasan, or ISIS-K operations in Europe.

The Moscow and Iran attacks demonstrated more sophistication, counterterrorism officials said, suggesting a greater level of planning and an ability to tap into local extremist networks.

“ISIS-K has been fixated on Russia for the past two years,” frequently criticizing President Vladimir Putin in its propaganda, said Colin Clarke, a counterterrorism analyst at the Soufan Group, a security consulting firm based in New York. “ISIS-K accuses the Kremlin of having Muslim blood in its hands, referencing Moscow’s interventions in Afghanistan, Chechnya and Syria.” —
