Somali pirates aboard the "Aris 13" opened fire March 16 on naval troops from the semiautonomous state of Puntland, sparking clashes between the two sides. The clashes started after naval forces tried to stop a boat carrying reinforcement pirates to the ship. Puntland dispatched naval forces to the area after the pirates seized the ship. One soldier was seriously injured in the fight. The pirates on the ship were continuing to receive reinforcements while regional forces mobilizing nearby in an effort to free the ship. The pirates moved the ship away from the coast after naval forces approached.
