A Chinese airline says a Bangkok-bound flight has made an emergency landing after an engine fire warning lit up.

China Southern Airlines said Flight 3081, which took off from the southern Chinese city of Guangzhou on Friday afternoon, made the emergency landing in Sanya, a city in Hainan province. No fire was found in the engine.

It said 14 passengers had minor scrapes and two others received ankle injuries when they were evacuated down slides.

The airline said it sent a plane to Sanya to fly the passengers to Bangkok.
