A super typhoon has made second landfall on the Philippines' main island of Luzon, with forecasters warning of "life-threatening storm surge", heavy rains and severe winds.

Typhoon Man-yi regained strength on Sunday afternoon, bringing heavy rain and powerful winds to the Philippines, hours after making landfall in a nation still recovering from a series of recent storms that killed more than 160 people and caused widespread damage.

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.
