Typhoon Man-yi has left at least seven people dead in a landslide, destroyed houses and displaced large numbers of villagers before blowing away from the northern Philippines, worsening the crisis wreaked by multiple back-to-back storms.

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 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.
