Thirteen people were killed Saturday when a passenger bus fell 70 metres (230 feet) down a gorge in southern Indian-administered Kashmir, police said.

"Thirteen died in the accident and the rest were injured," Pandey told AFP, adding three critically injured passengers were evacuated by air to a hospital in the city of Jammu.

Careless driving and bad, narrow and winding roads in the mountainous territory cause frequent accidents with passenger vehicles often slipping into deep gorges.

In India an average of 150,000 people die in road accidents each year.
