Search and rescue teams are combing the site where a 22-storey apartment building collapsed on Saturday night in the Colombian city of Medellin.
Eleven people are still missing beneath the rubble but firefighters are being hindered by the threat of further collapses.
“We have made several sweeps where we have tried to locate possible living victims, this is our main objective with the dogs, it is to find people who are still alive,” said firefighter Fabian Patino.
The building is located in one of Medellin’s most exclusive neighbourhoods. It was evacuated by the authorities on Friday after large cracks began to appear.
It is believed the missing are construction workers who were inside the building when it collapsed.
