ISIS calls attack "fiercest in years" and publishes purported image of 4 Moscow attackers

The Islamic State group, also known as ISIS, published an image Saturday purporting to show the four men who attacked the Crocus City complex near Moscow on Friday.

None of the men are identifiable in the image, which was published by the ISIS-affiliated Amaq agency. All of them are wearing balaclavas and the rest of their faces are blurred.

ISIS described the attack as the "fiercest in years," according to a translation of the message by the SITE Intelligence Group, which monitors terror groups’ propaganda.

Amaq provided details of the attack, saying three fighters attacked the gathered crowd at the venue with guns and knives while the fourth threw incendiary devices. It said the attack was preceded by an intensive surveillance operation of the venue.

It added that “the attack comes within the normal context of the raging war between the Islamic State and countries fighting Islam,” according to the translation by SITE.
