Officials from Russia's Investigative Committee in the republic of Tatarstan have said that authorities are looking for two local citizens allegedly involved in a July attack against two Islamic clerics.
The officials said that Robert Valeyev, 35, and Rais Mingaleyev, 36, could be among individuals who appear on a video in which a group of masked men took responsibility for the attack.
The video started circulating on the Internet on July 19, right after Tatarstan's Mufti Ildus Faizov was injured in a car bombing and his former deputy Valiulla Yakupov was shot dead near his house.
In a second video posted on the Internet on August 4 an Islamic militant who called himself "Muhammad -- the leader of Mujahidins of Tatarstan," took responsibility for the attacks.
Tatarstan’s investigators say the two videos were added to the investigation files.
