MOSCOW (Reuters) -An explosion on a bus killed two people and injured 17 in the southwestern Russian city of Voronezh on Thursday evening, TASS news agency reported, and counterterrorism officials were coordinating investigations into the blast.
The cause of the explosion, which took place near a bus stop when about 30 people were on board the bus, was still unclear.
Video footage published online showed the blast tearing the vehicle apart from the inside, with windows and debris sent flying in all directions.
