At least 19 people have been killed after a Bangladesh Air Force training jet crashed into a school and college campus in Dhaka, a fire services official said.
More than 50 people, including children and adults, were hospitalised with burns, a doctor at the National Institute of Burn and Plastic Surgery told reporters.
The incident occurred at the Milestone School and College in Dhaka's northern area of Uttara, officials said.
"Bangladesh Air Force's F-7 BGI training aircraft crashed in Uttara," the military's public relations department said in a statement.
Videos from the scene show flames and thick black smoke rising from the campus lawn, as onlookers watched from a distance.
Masud Tarik, a teacher at the school said he "heard an explosion".
"When I was picking (up) my kids and went to the gate, I realised something came from behind," he said.
"When I looked back, I only saw fire and smoke."
Firefighters were seen spraying water on the wreckage of the jet, which appears to have slammed into the side of a building.
Bangladesh's interim leader, Muhammad Yunus, called the losses "irreparable" and promised a full investigation and support for the victims and their families.
"The loss suffered by the air force … students, parents, teachers and staff, and others in this accident is irreparable," he said.
The crash comes just over a month after an Air India plane struck a medical college in Ahmedabad, India which killed 241 passengers and crew and 19 people on the ground.
