bursts into flames

AP - A plane has exploded into fire after landing at Khartoum's airport. About 200 passengers are thought to be aboard, but it is unclear how many might be casualties.

A Congolese jetliner carrying 79 passengers and crew crashed on takeoff Tuesday, careening off a runway into a busy neighborhood and bursting into flames.

At least 21 people were killed, but most of those aboard survived, an airline official said.
