Singapore Airlines said Monday there were no injuries when a jetliner caught fire after returning to Changi Airport because of an engine warning.

The Boeing 777-300ER was on its way to Milan when it turned back “following an engine oil warning message,” the company said.

It said the aircraft’s right engine caught fire after Flight SQ368 touched down more than four hours after taking off.

“The fire was put out by airport emergency services and there were no injuries to the 222 passengers and 19 crew on board,” Singapore Airlines said in a statement.

The passengers were transferred to another aircraft, it said.
