A passenger plane has caught fire before takeoff at an airport in South Korea, but all 176 people on board have been safely evacuated.

An Airbus plane has caught fire at an airport of South Korea's city of Busan, forcing the evacuation of all 176 people on board, fire authorities say. They say four people were injured as they were escaping the Air Busan aircraft on inflatable slides in the south-eastern airport on Tuesday evening.

Shares of Air Busan dropped on Friday, after a plane belonging to the budget carrier caught fire earlier this week.
