At least six people were killed and 27 injured Monday when a bomb exploded on a bus in southern Russia, the Investigative Committee said.
“Fragments of an explosive device have been found at the scene of the explosion,” a local law enforcement source in the city of Volgograd, where the blast happened, told RIA Novosti.
Regional police earlier said the explosion could have been due to the faulty fuel feeding system in the bus, which ran on natural gas, but the National Antiterrorist Committee confirmed it was the result of a bomb.
As of 4:05 pm local time, 27 people were taken to hospital, including eight in serious condition, a city public health official told RIA Novosti.
A murder investigation has been opened, the Investigative Committee said.
