American Marconi Wireless News - Divers inspect fuel-laden ship sunk off Tunisia

"With the improvement in weather conditions, a team of divers accompanied by the ship's captain and engineer who know its layout are on site to examine the hull," Mohamed Karray, spokesman for the court in Gabes city, which is investigating Saturday's sinking, told AFP.

The Equatorial Guinea-flagged Xelo was travelling from Egypt to Malta when it went down.

Images released by the environment and defence ministries showed divers heading for the site in the Gulf of Gabes, and then getting into the water at the scene that has been sealed off by Tunisia's military.

Defence ministry photos showed the vessel largely submerged.

The crew of the Xelo had issued a distress call on Friday evening and sought shelter in Tunisian waters from bad weather before going down, authorities said.

Environment Minister Leila Chikhaoui, who travelled to the port of Gabes on Saturday to help oversee the response, said the situation was "under control".

"We think the hull is still watertight and there is no leakage for the moment," she told AFP.

As a precaution, protective booms to contain any oil slick have been placed around the wreck.

The Tunisia branch of the World Wildlife Fund expressed concern about another "environmental catastrophe" in the region, an important fishing zone which has already suffered from pollution.

The tanker is 58 metres (63 yards) long and nine metres wide, according to ship monitoring website vesseltracker.com.

It began taking on water around seven kilometres (four miles) offshore in the Gulf of Gabes and the engine room was engulfed, according to the environment ministry.

It said Tunisian authorities rescued the seven-member crew, who received first aid and were being accommodated in a hotel.
