BANGALORE (AFP) At least 30 people, including 10 children, were burnt alive on Sunday when a bus bound for the southern Indian city of Bangalore ploughed into a roadblock and caught fire, police said. The state-owned vehicle veered off a small bridge after colliding with the roadblock in the dark and fell into a ditch. , local superintendent of police Labhu Ram told AFP from the accident site by phone. The bus caught fire when the diesel tank exploded on impact, he said. The bus had 64 passengers on board and was on its way from Surpur in southern Karnataka state to the IT hub of Bangalore, 600 km away. At least three surviving passengers were in a serious condition. State transport minister R Ashok, who visited the accident site, told reporters that preliminary reports suggested the driver was at fault.
