Chechen police operatives and the local Federal Security Service (FSB) department have killed a man suspected of involvement in a hostage-taking raid on the town of Budyonnovsk in the Stavropol territory in 1995. Police officers attempted to detain Umar Isakov, who was on the federal wanted list, in the community of Kadi-Yurt in Chechnya's Gudermes district on Friday, the Chechen Interior Ministry told Interfax on Saturday. The man attempted to throw a grenade at the policemen and was killed. "Two members of illegal armed units were also detained in the Achkhoi-Martan district," the Interior Ministry said.
