ROME, Nov 10 (Reuters) - The right engine of a Boeing

787-9 Dreamliner operated by Chinese carrier Hainan

Airlines caught fire shortly after take-off from

Rome's Fiumicino airport this morning, an Italian airport

official said.

The plane, bound for the Chinese city of Shenzhen, turned

back and landed safely after dumping fuel over the sea.

The cause of the fire was unclear, the official said, adding

that there were no delays to air traffic at Fiumicino.
