On Sunday, the Dagestan affiliate of the Caucasus Emirate, a separatist group in Russia that has been tied to al Qaeda by the United Nations, issued a statement denying responsibility for the attacks in Boston. Here's a translation by the jihadist media clearinghouse blog Jihadology:
[T]here are speculative assumptions that [Tamerlan Tsarnaev] may have been associated with the Mujahideen of the Caucasus Emirate, in particular with the Mujahideen of Dagestan.
The Command of the Province of Dagestan indicates in this regard that the Caucasian Mujahideen are not fighting against the United States of America. We are at war with Russia, which is not only responsible for the occupation of the Caucasus, but also for heinous crimes against Muslims.
The statement also stressed that the leader of the Caucasus Emirate, Doku Umarov, has discouraged targeting civilians and blamed speculation about the Tsarnaevs' connection to Chechen separatists on Russian propaganda.
The Caucasus Emirate has been under particular scrutiny for the attacks, given the Tsarnaevs' Chechen heritage and older brother Tamerlan's trip to Chechnya and Dagestan last year, which some reports have tied to his radicalization.
The statement does not definitively indicate that the Tsarnaevs are not connected to the Caucasus Emirate, however. "The Caucasus Emirate is a very decentralized structure organizationally so I wouldn't necessarily say they speak on behalf of other wilayah or jama'at or even the emir Dokku Umarov," writes Aaron Zelin, the Richard Borow fellow at the Washington Institute for Near East Policy and founder of Jihadology, whom FP reached by email this morning. "The Caucasus Emirate is the main jihadi umbrella, but there are a bunch of wilayah and jama'at that work under it. I don't think we know enough information to determine if they could have worked with others."
The Dagestan affiliate of the Caucasus Emirate is not the first jihadist group to deny involvement in the attacks. The Pakistani Taliban issued a statement denying responsibility almost immediately after the bombings last week, with a spokesman for the organization saying, "Certainly, America is our target and we will attack the U.S. and its allies whenever the [Pakistani Taliban] finds the opportunity, but we are not involved in this attack."
