A rescue vessel and several commercial ships battled strong waves Wednesday to try and pull 11 crewmen from the raging sea in the northern Philippines after their cargo vessel capsized overnight. Nine sailors were rescued and the remaining 11 were wearing life jackets and clinging to ropes tied to their vessel, coast guard Cmdr. Rudyard Somera said. The stricken vessel, Mark Jason, was on its way to Batanes islands in the northern Philippines when it encountered strong waves late Tuesday. Somera said the captain of another vessel nearby reported to the coast guard that the crew was abandoning the stricken ship. He tried to get closer but couldn't because of strong waves, Somera said. "They trained their search lights on the vessel and observed that the crew were wearing life jackets," he said.
