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 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.

At least eight people have died, nearly 8,000 homes have been damaged or destroyed and more than 100 cities and towns are without power in the wake of the sixth storm to batter the Philippines in a month.
