A truck loaded with concrete chips crashed into a passenger bus in southern India early Monday, killing at least 20 people and injuring about two dozen, local authorities said.

The state-run transport bus was carrying around 70 passengers to Hyderabad city in India's southern Telangana state when a truck coming from opposite direction collided with it near the town of Chevella, local district official K. Chandrakala told The Associated Press.

The front of the bus was badly mangled, trapping several passengers inside.

Rajendra Prasad, superintendent at Chevalla hospital said 20 bodies have been moved to the mortuary and will be handed over to their families after verification.

The accident came a day after a minibus carrying passengers in western state of Rajasthan rammed into a parked truck late Sunday, killing at least 15 people and injuring two others.
