A government official says that 15 people were killed and 40 were seriously injured in a bus crash in Cameroon's northwest.

West Regional Governor Samuel Diboa says that the bus was heading to Yaounde when it crashed into a trailer truck parked on the side of the road and carrying a bulldozer early Monday. He said the bus burst into flames.

Diboa said that the 40 injured people were rushed to hospitals.

At least 1,200 people died from road accidents in 2010, according to data from the West African nation's ministry of transport.

The ministry says recklessness, high speed drunk driving and the poor state of most of the vehicles has led to a high death rate from road accidents in Cameroon.
