Story highlights Rustam Magomedovich Aselderov pledged allegiance to ISIS in 2014, Russia says

He was wanted in connection with the 2013 terrorist attacks in Volgograd

(CNN) The leader of a North Caucasus ISIS branch was killed in a special operation conducted by Russian Federal Security Service forces in collaboration with the Ministry of Interior, the security service said in a statement Sunday. Rustam Magomedovich Aselderov, known as Abu Muhammad, and four militants close to him were killed in an exchange of fire with government forces Saturday near Makhachkala, the capital of Dagestan, the statement from the FSB said. The statement said authorities found "automatic weapons and a large amount of ammunition and explosives" at the house during the December 3 raid. Russian security agency FSB said in a statement on Sunday that Aselderov, although operating in Dagestan, pledged allegiance to the Islamic State group in 2014. The regional office of the Russian Investigative Committee identified one of the five as 35-year old Rustam Aselderov, who was wanted for his suspected role in several attacks, including a double bombing in 2013 on a bus and at a train station in southern Russia that killed a total of 34 people.
The Russian Federal Security Service claims to have killed Rustam Asildarov, the leader of the Islamic State of Iraq and the Levant's Caucasus Province and four other militants in the Dagestan region.
