The number of people who've died after a block of flats collapsed in Florida has risen to four.
But with 159 others still missing, rescue teams fear that figure could rise considerably.
The building near Miami was undergoing construction work before coming down in the early hours of yesterday.
A report's emerged which claims the apartment block was built on reclaimed wetlands and had been slowly sinking.
No official reason for the collapse has been given yet.
Rescuers are using specially trained dogs and listening equipment to try to find survivors in the rubble.
President Biden has declared an emergency - which means federal agencies can step in to help.
Our thoughts and prayers are with the families in Surfside as we respond to this tragedy in our community. — Mayor Francis Suarez (@FrancisSuarez) June 24, 2021
