Suicide bomber in Russia’s south kills 1, wounds 10

A policeman has been killed and at least ten people were injured by a suicide bomber in Russia's southern republic of Dagestan.

The blast went off at a checkpoint as the attacker attempted to drive his car into a police station in the city of Khasavyurt.

A criminal investigation has been launched into the accident.

The violence follows two anti-terror operations by security forces in the republic of North Caucasus this week, in which four militants were killed.

Russia’s south remains a volatile region in spite of the authorities’ efforts.
