GUWAHATI, India (AFP) - At least 45 people were killed and scores injured Tuesday in two bus accidents in India, police and officials said. Twenty-three people were killed and dozens wounded when a heavily overcrowded speeding bus smashed into a truck in India's northeastern Assam state. "The bus had a capacity of 35 passengers, but was carrying 67 people. The driver lost control as it was moving at a very high speed and hit the truck in the rear," local police chief Parthasarathi Mahanta told AFP. The accident took place on a national highway west of Guwahati, the main city in Assam state. In the other accident, in the Himalayan state of Uttarakhand, 22 people were killed and 23 others critically injured when a large rock fell on a bus. A thousand people have died this year in road accidents in the northern Uttarakhand state. India has the highest annual road death toll in the world, often caused by bad roads, overcrowding and poor maintenance of vehicles.
