A Bangladesh air force training aircraft has crashed into a college and school campus in the capital, Dhaka, killing at least 31 people, including the pilot, according to the military.

The F-7 BGI aircraft crashed into the campus of Milestone School and College in Dhaka’s Uttara neighbourhood at about 1pm (07:00 GMT) on Monday, when students were taking tests or attending regular classes.

Most of the injured were aged between eight and 14, said Mohammad Maruf Islam, the joint director of Dhaka’s National Burn and Plastic Surgery Institute, where many victims were treated.
