Unknown suspects shot dead two policemen in the early hours of Saturday in Russia's North Caucasus republic of Dagestan, a local police spokesman said.
The spokesman said two police officers were patrolling a municipal park in the town of Izberbash shortly after midnight on Saturday, when they stopped unidentified people to check their IDs.
"During the inspection of the documents, unknown suspects opened gunfire on the policemen killing Sgt. Alkhasov and Lt. Shaknovazov," the spokesman added.
More that a decade after the end of a federal war against separatists in Russia's North Caucasus republic of Chechnya, Russian security forces continue to fight militants in other regions in the area, who stage frequent attacks on security forces, police and civilians.
