Unknown gunmen have shot dead two policemen in Russia's volatile Caucasus in the latest attack against local authorities, police said on Saturday.
Assailants driving a Lada shot at a car carrying three traffic police outside the Dagestani town of Kizilyurt late Friday and fled, a police spokesman told AFP.
"Two people died," he said, adding that a third policeman received no injuries.
The spokesman said it was not immediately clear who was behind the attack, adding an operation was under way to catch the gunmen.
In February, a man shot into a crowd leaving a church in Dagestan, killing five people and wounding at least five others.
