Two police officers were killed and about 20 wounded in two explosions in the Russian North Caucasus republic of Dagestan, a law enforcement source said Tuesday.
A female suicide bomber blew herself up near a police station in the village of Gubden on Monday evening, killing one policeman and injuring several.
In a short while, a second explosion followed. A Lada Priora car, stopped at the Gubden checkpoint for an inspection by security guards as it was heading toward the scene of the previous explosion, exploded killing one policeman and leaving about 17 people wounded.
Earlier it was reported that five people were injured in the second blast.
An investigation is underway.
Terrorist attacks and shootouts with police are common in Russia's troubled North Caucasus republics, especially Dagestan and neighboring Chechnya and Ingushetia.
