A policeman was killed and four others were wounded in attacks in restive Chechnya, the Russian republic's Interior Ministry said Sunday. The policeman was shot late Saturday in a central area of Grozny, the Chechen capital, the ministry said. Two other shooting attacks, each wounding two officers, took place Saturday in other areas of Chechnya, the ministry said. Major fighting between separatist rebels and Russian forces died down early in the decade, but insurgents continue to mount small hit-and-run attacks on police and soldiers. Chechnya is also plagued with criminal activity and some attacks on police are believed to be connected to gangs rather than rebels.
