Manila - Air force helicopters joined Tuesday in the search for at least 28 people missing after an overloaded boat capsized and sank in the northern Philippines, killing at least 27 people.
Lieutenant Commander Ferdinand Panganiban, a local coast guard commander, said 45 people survived the sinking Sunday of the MB Maejan off the coast of Ballesteros town in Cagayan province, 420 kilometres north of Manila.
Panganiban said rescuers were scouring nearby islands and islets in hopes of recovering more survivors who might have been able to swim to safety.
Maejan left Calayan Island for the mainland town of Aparri when it was battered by huge waves and strong winds, causing it to capsize.
