“Vilayat Dagestan, a jihadist group that is part of the Caucasus Emirate, an al Qaeda-linked group operating in the North Caucasus, has issued a statement on the Boston Marathon bombings.
The group released the statement on its main website earlier today, citing ‘speculation’ in the press that one of the bombers ‘could be affiliated with the mujahideen of the Caucasus Emirate, in particular, the mujahideen of Dagestan.’ The statement has been translated by the SITE Intelligence Group.”
