Typhoon Man-yi has left at least seven people dead in a landslide, destroyed scores of 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 ripped through the Philippines’ largest island on Sunday, knocking down houses and sending more than half a million people to emergency shelters, as rare back-to-back storms cause havoc across an exhausted nation.

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.
