Powerful Typhoon Soudelor is battering Taiwan with strong winds and heavy rain, leaving at least four people dead.
The storm - with winds of more than 230km/h (142mph) - made landfall on the eastern coast early on Saturday and is now moving across the island. It is ripping up trees and tearing down billboards, and triggered a landslide in at least one village.
About two million households have been left without electricity.
Rail services and flights have been cancelled and all schools and offices closed.
