ISIS-K, group tied to Moscow attack, has grown bolder and more violent
Few know better than the Taliban what a relentless foe the Islamic State’s affiliate in Afghanistan can be.
Much of the West considers the Taliban, which reclaimed power in the country in 2021, to be an extremist Islamic movement. But the Islamic State-Khorasan, the affiliate that has been linked by U.S. officials to a terrorist attack in suburban Moscow on Friday, has slammed the Taliban government, calling the group’s version of Islamic rule insufficiently hard-line.
The Islamic State-Khorasan, or ISIS-K, is one of the last significant antagonists that the Taliban face in Afghanistan. It has carried out a bloody drumbeat of attacks throughout the country in recent years, seeking to use the violence to undermine the Taliban’s relationships with regional allies and to portray the government as incapable of providing security in Afghanistan, experts say.
In the months after the Taliban seized power, ISIS-K carried out near daily attacks on their soldiers at roadside checkpoints and in neighborhoods that are home to the country’s Hazara ethnic minority. The following year, ISIS-K fighters attacked the Russian Embassy in Kabul, Afghanistan, tried to assassinate Pakistan’s top diplomat to Afghanistan and sent gunmen into a prominent hotel in Kabul that was home to many Chinese nationals, seeking to undermine the Taliban’s promise of restoring peace.
More recently, ISIS-K’s attacks have grown bolder and stretched beyond Afghanistan’s borders: The group killed at least 43 people in an assault on a political rally in northern Pakistan in July. It killed at least 84 people in two suicide bombings in Iran in January. Now, U.S. officials say ISIS-K was behind the attack in Moscow, which killed at least 133 people.
In recent months, ISIS-K has threatened attacks against the Chinese, Indian and Iranian embassies in Afghanistan. It has also released a flood of anti-Russian propaganda, denouncing the Kremlin for its interventions in Syria and condemning the Taliban for engaging with Russian authorities decades after the Soviet Union invaded Afghanistan.
“ISIS-K has long been motivated by the logic of outbidding in its attacks,” said Asfandyar Mir, a senior expert at the United States Institute of Peace. “It seeks to outperform rival jihadis by carrying out more audacious attacks to distinguish its jihadi brand and assert leadership of the global jihadi vanguard.”
ISIS-K was established in 2015 by disaffected fighters of the Pakistani Taliban, an ideological twin and ally of the Taliban in Afghanistan. ISISK’s ideology spread partly because many villages in eastern Afghanistan and Pakistan are home to Salafi Muslims, the same branch of Sunni Islam as the Islamic State. The Taliban, in contrast, mostly follow the Hanafi school of Islam.
From its early days, ISIS-K has been at odds with the Taliban, fighting over turf in eastern Afghanistan and later denouncing the Taliban’s new government for not instituting what it views as true Shariah law. ISIS-K propaganda has sharply criticized the Taliban for working to establish diplomatic relations with non-Muslim countries, including the United States and Russia, describing the efforts as a betrayal of the global jihadi struggle.
Before the U.S.-led war in Afghanistan ended in 2021, American airstrikes and Afghan commando raids had contained ISIS-K mostly to eastern Afghanistan. But after the withdrawal of Western troops, the Islamic State’s reach expanded to nearly all of the country’s 34 provinces, according to the United Nations Assistance Mission in Afghanistan.
Since seizing power, the Taliban have carried out a relentless and often ruthless counterterrorism campaign to squash ISIS-K. Those efforts have prevented the group from taking any territory in Afghanistan and pushed many of its fighters into Pakistan, experts say. Taliban security forces killed at least eight of ISIS-K’s leaders in the country last year, according to U.S. officials.
The crackdown drew condemnation from human rights groups that claimed Taliban security forces were summarily executing and forcibly causing disappearances of people accused of being affiliated with the Islamic State in eastern Afghanistan, the group’s historic stronghold.
U.N. monitors also cautioned this year that the Taliban’s counterterrorism operations against ISIS-K “appear to be more focused on the internal threat posed to them than the external operations of the group.”
But even as ISIS-K cells have come under mounting pressure from Taliban security forces, the group has proved resilient and remained active across Afghanistan, Pakistan and Iran. Just a day before the attack near Moscow, the group carried out a suicide bombing in Kandahar, Afghanistan — the birthplace of the Taliban movement — sending a powerful message that even Taliban soldiers in the group’s heartland were not safe.
