At least 32 people have been killed and dozens injured after two buses collided head-on in northwest Bangladesh, police say.

The accident took place on Monday at Baraigram in Natore, 220km from the capital Dhaka.

The death toll could rise further as some of the injured are in a critical condition, police official Mohammad Manirul Islam told Reuters news agency.

A three-member committee has been formed to investigate the accident.

Road accidents kill around 10,000 people a year in impoverished Bangladesh. They are often blamed on reckless driving, poor roads and aged vehicles.
