The death toll from a train crash in south-western Pakistan rose to 19, officials said Wednesday, as investigators looked into whether it was an accident or sabotage, dpa reported. The train carrying around 300 passengers from the remote province of Balochistan to Rawalpindi city near the capital Islamabad derailed on Tuesday. Twelve people were declared dead after the incident, while "seven more people succumbed to their injuries overnight," provincial Home Minister Sarfraz Bugti said. At least a dozen casualties were in critical condition, Bugti said.
