The militant is said to have organized the murders of officials working in the Office of the Public Prosecutor and Kabardino-Balkarian police officers. In July, he allegedly staged the assassination of a prosecutor’s office employee in front of the victim's 10-year-old son.
"The militant leader was killed in a firefight. According to preliminary data, he has been identified as Robert Zankishev, with alias Abdullah, a leader of one of the armed militant groups in Kabardino-Balkaria," NAK said in a statement.
According to NAK, a pistol, an improvised explosive device with a total capacity of about 3 kilograms of TNT as well as ammunition was seized in the apartment where Zankishiev was holed up with a number of other militants, in a multistory residential building in the city of Nalchik.
Earlier in the day, a counter-terrorism operation was launched in Kabardino-Balkaria. Residents of nearby building were evacuated to avoid casualties.
