The Takfiri group, ISIL, has claimed responsibility for a suicide attack that killed a policeman in Russia's volatile region of Dagestan.

An ISIL militant "detonated his explosives belt at a checkpoint of the Dagestani police... killing and wounding several of them," according to an ISIL statement distributed online.

Local police had said Wednesday's attack had involved either a car exploding at the checkpoint or the occupants of a vehicle throwing an explosive device at a police car. One policeman was killed and another wounded, officials said.

The attacks came after Syrian troops backed by Russian forces secured an important victory against ISIL by recapturing the ancient city of Palmyra, which the Takfiris had overrun in May last year.
