The number of people listed as missing after the collapse of a 12-storey building in the US city of Miami has risen to 159, officials say.
Four people are known to have died.
The mayor of Miami-Dade says they “still have hope” of finding survivors. Search teams working around the clock have reported hearing people banging beneath the debris.
What caused the 40-year-old building to collapse early on Thursday morning remains unclear.
