At least 27 people were killed in a bus accident on Saturday in southwestern Tanzania, a senior police officer said.

A bus tried to overtake a car and crashed into a truck about 50 kilometers (31 miles) from the southwestern Tanzanian town of Mbeya, said Stephen Mwinamila, the regional traffic commander.

Mwinamila said two pedestrians were among those killed. Forty-three people were seriously injured and have been admitted to Mbeya Hospital, he said.

The accident is one of the deadliest in the region in the past two years.
