A Singapore Airlines flight caught fire after the plane returned to Changi Airport because of an engine warning, according to the airline, which said no injuries were reported.
An airline statement said the Boeing 777-300ER was on its way to Milan when it turned back "following an engine oil warning message."
The aircraft's right engine caught fire after Flight SQ368 touched down more than four hours after takeoff, according to the airline.
"The fire was put out by airport emergency services and there were no injuries to the 222 passengers and 19 crew on board," the airline statement said.
Airline officials said the passengers were transferred to another aircraft that was set to depart for Milan later Monday.
