A powerful typhoon has made landfall in the northern Philippines, where authorities have ordered more than 100,000 people to seek refuge from heavy rains and gusts of up to 170km per hour that have blown away roofs, uprooted small trees and toppled power lines.

At least one person, a baby, was killed when Typhoon Nesat made landfall before dawn on Tuesday over the eastern mountainous region of Isabela and Aurora provinces, facing the Pacific Ocean on Luzon island.
