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 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.

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.
