A tanker carrying diesel fuel collided with another ship in the English Channel Friday but there was no immediate report of any spillage, the Maritime and Coastguard Agency said.

The incident was reported at 1015 GMT about 25 miles south of Beachy Head, southeast of London, the agency said.

The Maltese-registerd tanker Shakhdag, carrying 48,500 tons of fuel oil, collided with the MV Willy, which was unloaded, the agency said.

The Shakhdag, with 21 people on board, suffered minor damage to the stern but carried on to its desination -- Portland in southwest England.

The Willy, with 13 people on board, suffered some damage. The Coastguard said a helicopter carrying a marine surveyor was dispatched to investigate.
