A strong earthquake in Taiwan has killed at least two people and injured more than 100 others, officials say.

The powerful 6.4-magnitude tremor struck at 23:50 (15:50 GMT) about 20km (12 miles) off the island’s east coast.

Rescuers are trying to free people from a partially collapsed hotel and a residential building, officials say.

Photographs show tilting and collapsed high-rise buildings, scattered debris and extensive damage to roads in the area.

The lower basement and ground floor of the 10-storey Marshal Hotel have given way. At least three members of staff are thought to be stuck inside, state media says.
