At least six were killed and more than 30 injured Monday when a suicide bomber detonated an explosive device aboard a bus in the Russian city of Vogograd. The blast was captured on a driver’s dash cam.
According to the BBC, the suicide bomber was a female member of the Islamic insurgency in Dagestan in the North Caucasus.
The region has seen a rise in attacks in recent years, and more are expected as the 2014 Winter Olympic Games draw near.
