Four police killed in ambush in Russia’s Dagestan: official

Four police were shot dead on Sunday in an ambush by unknown gunmen in Russia’s violence-plagued Caucasus region of Dagestan, the local interior ministry said.

The police drove to the village of Burshi where they had received a report of a robbery, and were shot dead as they were leaving the area, Russian news agencies quoted the interior ministry as saying.

A largely Muslim region on the Caspian Sea, Dagestan has become Russia’s worst trouble spot in recent years with almost daily attacks on the security forces blamed on Islamist militants.
