Russia's Investigative Committee says three militants killed in Tatarstan's capital were suspects in high-profile attacks against Islamic leaders in the Russian region earlier this year.
In July, Tatarstan's Muslim religious leader, Mufti Ildus Faizov, was injured in a car bombing and his former deputy, Valiulla Yakupov, was shot dead in attacks conducted by suspected followers of radical Islam.
Two members of the Federal Security Service were killed in the fighting in Kazan along with the three militants on October 24.
Tatarstan's Interior Ministry said the militants blocked a street in Kazan and fired at police.
The ministry added that one of the dead men appeared to be wearing a suicide belt packed with explosives.
