Somali forces have been sent to free the hijacked ship, a regional police official said on Tuesday.
"We are determined to rescue the ship and its crew. Our forces have set off to Alula. It is our duty to rescue ships hijacked by pirates and we shall rescue it," Abdirahman Mohamud Hassan, director general of Puntland’s marine police forces, told Reuters by phone.
Puntland is a semi-autonomous northern region. Alula is a port town there where pirates have taken the Aris 13 and her eight Sri Lankan crew.
