British special forces have rescued an Italian ship hijacked by Somali pirates, the Italian foreign ministry has confirmed.

In a joint operation with the Americans, a team of special forces met no resistance as they prepared to storm the 56,000-ton bulk carrier Montecristo - capturing the pirates and freeing the hostages.

The ship was hijacked 620 miles off Somalia on Monday by pirates in a small boat, according to the owners.

The Italians said that 11 pirates had been detained.

All of the 23-man crew from Italy, India and the Ukraine have been rescued.

Italy's Foreign Ministry expressed "great satisfaction" in the operation to save the D'Alessio Group-owned cargo ship.
