On-Don, Russia, Safar 12, 1432, Jan 16, 2011, SPA-- A policeman and a cattle-breeder have been killed in attacks in a village in Kabardino-Balkariya, part of the Russian Caucasus region that is plagued by separatist violence and crime. It was not immediately clear if authorities believed the Saturday attacks in the village of Islamei were related, as AP reported. A spokesman for the republic's Interior Ministry, Maxim Ushanov, said Sunday that the cattle-breeder was shot to death by an insurgent angered that the victim had refused to make a contribution to the rebel movement. Ushanov said the policeman was killed when an attacker armed with a pistol broke into his residence and opened fire.
