Greek authorities say a fire has broken out on a US-flagged vehicle carrier ship carrying 28 people off the country's main port of Piraeus.
A coast guard statement says firefighting ships are trying to extinguish the blaze on the Alliance Norfolk. There are 23 crew members and five passengers on board.
The cause of Monday's blaze was not immediately clear.
The 57,000-ton, 200-meter (yard) vessel was en route from the United States to Saudi Arabia with a consignment of cars and had moored for an inspection just off Piraeus, the port of Athens.
