Taiwan moved thousands of people to safety on Wednesday as the island braced for its first typhoon this year, airlines cancelled domestic flights and authorities issued warnings about floods and high seas.

Typhoon Danas, categorised at the weakest typhoon level, was expected to hit the eastern county of Yilan late on Thursday. It was moving across the ocean in a northwesterly direction at 18km per hour.

Authorities have said more than 2,000 people were moved to safety, most of them tourists on islands off its east coast.
