Hundreds of people are feared trapped in collapsed buildings after a 6.4 magnitude earthquake struck Taiwan. 'Multiple' buildings - including at least one residential block - are said to have fallen following the quake which shook the island at about 4am on Saturday. Reports emerging suggest Tainan, on the south-west coast, was the worst affected, with pictures of buildings partially or completely destroyed circulating on social media, while video footage shows rescue workers wading through water after the mains burst.
