MOSCOW, August 2 (RIA Novosti) - Russia's security chief said Wednesday he was convinced that killers of five Russian embassy employees in Iraq would be found.

One embassy employee was shot June 3 in an attack on a car. Four others were abducted and executed later by an al-Qaeda linked group.

"All special services are involved [in the investigation]," Nikolai Patrushev, the head of the Federal Security Service and the chairman of the national anti-terrorism committee, said adding that President Vladimir Putin's orders would be fulfilled.

President Vladimir Putin gave orders in June for the killers of the diplomats to be found and killed.
