MANILA, Philippines — A powerful typhoon wrecked houses, caused towering tidal surges and forced hundreds of thousands of people to flee to emergency shelters as it cut across the northern Philippines on Sunday in the sixth major storm to hit the country in less than a month.

A super typhoon barreled toward the Philippines’ largest island on Sunday, as more than half a million people sought shelter from the latest in a string of powerful storms to threaten the country.

MANILA (Reuters) -Philippine authorities issued an urgent appeal on Saturday for residents in low-lying areas and coastal towns to move to safety as super typhoon Man-Yi gained strength on its approach towards the country's main Luzon island.
