Federal Security Service officer killed in North Caucasus

A Russian Federal Security Service (FSB) officer has been killed in the capital of the Russian North Caucasus republic of Dagestan, investigators said on Monday. "The incident occurred at about 11 p.m. Moscow time [1900 GMT] Sunday. An unknown assailant shot FSB Lieutenant Colonel Magomedov on a Makhachkala street," a spokesman said."The officer died of the wounds he received. The criminal escaped," he said. An investigation is underway. More that a decade after the end of a federal war against separatists in Chechnya, Russian security forces continue to fight militants, who stage frequent attacks on security forces, police and civilians, in other regions in the area, including Dagestan.
