Rescuers in Taiwan are working to find more than 100 people still missing more than 24 hours after the island was hit by a powerful earthquake.
At least 124 people are missing after the collapse of the 17-storey block, officials say.
Rupert Wingfield-Hayes saw evidence that tin cans were apparently used as filler inside some of the concrete beams.
