Another suicide bombing claimed lives of 14 passengers on a trolley bus in south-west city of Volgograd in Russia on Monday.
According to state-owned agency Russia Today, the explosion was set off by the bomber when the bus was located near one of the busy markets in the city, injuring 27 others, out of whom two are in critical condition.
The authorities have shutdown communication services for mobile phones in the area as the bomb in the trolley bus was detonated by a remote device, tweeted Ina Ruck, a journalist for ARD media.
Members of the emergency services work at the site of a bomb blast on a trolleybus in Volgograd December 30, 2013.
The trolley bus was burnt-out and reduced to its metal carcass, as per the images. The scene showed dead bodies of the passengers scattered around the trolley bus.
The Russian authorities have announced a new flight from capital city of Moscow to Volgograd 'with medical equipment and personnel for possible transportation of the blast victims to the capital', the report said.
The Russian Investigative Committee has termed the blast as another 'terrorist attack', after 17 people were killed in an explosion at the city railway station on Sunday. At least 44 people were injured, out of whom 38 were hospitalised.
After claiming that it had been a 'woman suicide bomber' the Russian Anti-terrorism Committee has not ruled out that both a man and a woman could have detonated the bomb when a police officer tried to approach the metal detector at the station. No terrorist group has claimed responsibility for the twin bombings.
