FACTBOX: Ships held by Somali pirates

(Reuters) - U.S. Navy special forces freed an American ship’s captain and killed three Somali pirates holding him hostage in a lifeboat, ending a five-day standoff.

The Maersk Alabama, with a crew of 20 U.S. sailors, was seized on April 8 but the crew retook control after a confrontation with the pirates and the captain was taken hostage.

Somali pirates have vowed to avenge the shooting of their comrades on the Maersk Alabama, as well as from the French military assault to rescue a yacht on Friday in which two pirates were killed and three captured.

However, the pirates have released the Norwegian-owned tanker Bow Asir, which was taken at the end of March. The 27-member crew were unharmed.

Pirates have attacked at least 15 vessels off the coast of Somalia last month after only two in January and February.
