An engine fire forced a Korean Air jet to scrub takeoff at Tokyo's Haneda airport on Friday but its 320 passengers and crew managed to evacuate safely, transport ministry and airport officials said.

Seven of the 302 passengers and 17 crew members on the Seoul-bound Boeing 777-300 sustained scratches while using the escape chutes, Korean Air Lines said.

The plane was preparing for takeoff when an air traffic controller noticed that its left engine was on fire, the ministry and airport officials said. The incident was reported to authorities at around 12:44 p.m.
