A powerful earthquake struck southern Taiwan early on Saturday near the city of Tainan, toppling at least one apartment building and collapsing other structures.
A 17-story building has collapsed in Tainan, a local fire brigade official told Reuters. They added that 123 people have been rescued from the building.
"There are 60 households in that building," said Tainan City Government Fire Bureau information officer Lee Po Min, estimating that there might be about 240 people living there.
At least five aftershocks of 3.8-magnitude or more shook Tainan about half an hour after the initial quake, according to Taiwan's Central Weather Bureau.
Taiwan's Formosa TV showed images of police, firefighters and some troops in camouflage uniforms at the site of a collapsed residential building and said its reporters could hear the cries of some residents trapped inside.
