Passengers evacuated from an Air Busan plane that was engulfed in flames this week at a South Korean airport will have their checked baggage returned to them, after authorities on Friday deemed the jet safe for a full investigation.

The fire broke out in the back of the cabin, officials said. All 176 people on board, including passengers and crew members, were evacuated, some with minor injuries.

South Korean officials are launching an investigation into the cause of the fire that engulfed an Air Busan passenger plane, with eyewitness accounts suggesting a power bank may have sparked the blaze.
