Second tanker in three months hijacked off Yemen by suspected Somali pirates

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.Speaking to the BBC, three Puntland security officials separately identified the craft hijacked on Friday as a tanker named MT Astana.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.
