Two Sudanese military aircraft collided while landing at Khartoum International Airport forcing it to close for several hours, an airport spokesman said.
The transport aircraft were returning from training flights when the collision occurred, a military spokesman said.
The planes, one an Antonov 26 and the other an Antonov 32, suffered severe damage but there were no casualties, the spokesman said.
Civil aviation spokesman Abdel-Hafez Abdel-Rahim said international flights were diverted to Port Sudan airport while Khartoum was closed. It opened later.
