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.

A powerful typhoon forced hundreds of thousands of people to flee to emergency shelters as it cut across the northern Philippines on Sunday.

Super Typhoon Man-yi uprooted trees, brought down power lines and ripped off corrugated iron roofing as it swept across the storm-weary Philippines on Sunday, following an unusual streak of violent weather.
