MOSCOW: Five policemen were killed and 10 wounded Wednesday in an explosion in Dagestan, the Russian republic in the restive North Caucasus region, Ria-Novosti news agency reported quoting a local police official.

A booby-trapped car exploded near the traffic police headquarters in Makhachkala, the Dagestan capital, the official said.
