Pirates have hijacked a tanker in the Gulf of Aden off the coast of Yemen, according to a UK maritime safety organisation (UKMTO) and Somali security officials.
The UKMTO said a "vessel was boarded by unauthorised personnel" as it sailed east, adding that other ships were "advised to transit with caution". Officials from Somalia's semi-autonomous Puntland region said the attackers were Somali.
This is the second hijacking of a vessel off the coast of Yemen since May, when the MT Eureka was seized near the port of Qana. Two other ships were boarded by pirates in the Indian Ocean in April.
There have also been several unsuccessful attacks in a region where piracy appears to be making a comeback.
Until three years ago these kinds of incidents had almost disappeared in this area once notorious for hijackings, following a concerted security operation involving several navies.
They added that it was seized by seven gunmen who had set off from a remote area near the Puntland port town of Garacad before making their way to the Gulf of Aden.
The MT Asana, sailing under a Tanzanian flag, was en route to the port of Bosaso in Puntland, when it was boarded 65 nautical miles off Yemen.
Whereas the Indian Ocean is heavily patrolled by the European Union Naval Force, which oversees anti-piracy operations in Somalia, the Gulf of Aden is more lightly protected.
According to the Puntland officials, this could explain why it has now become an area of operation for the pirates.
