The mercenary and his four accomplices were killed Sunday in a special operation.
"In Khasavyurt, the Dagestan branch of the Federal Security Service carried out a special operation from 6:00 a.m. (3:00 a.m. GMT) to 10 a.m. (7:00 a.m. GMT), as a result of which foreign terrorist and mercenary Abu Havs and his four accomplices were killed," the security service said.
Emir Ibn al Khattab was killed in March 2002, in an operation by Russia's Federal Security Service (FSB). Khattab was directly involved in preparing and perpetrating an attack on Chechnya's capital Grozny in August 1996, as well as a terrorist attack on Buinaksk in December 1997.
After Khattab was killed, Abu Havs was an organizer of terrorist activity in the North Caucasus and was preparing terrorist acts on the territory of Dagestan, the local security service said.
At the same time, the Federal Security Service has not yet commented on the report about the killing of Abu Havs.
