Rescuers recover three bodies from the rubble of three buildings that collapsed in downtown Rio Wednesday.
Authorities say the cause of the collapse could have been a structural failure, highlighting concerns about Rio's infrastructure ahead of the 2014 soccer World Cup and the 2016 Olympics.
The buildings, one 20 floors high, collapsed on Wednesday night in a cloud of dust and smoke just one block away from the city's historic Municipal Theater.
Rescue teams pulled six people alive from the rubble. More than a dozen people are still missing.
The buildings were mostly used for office space during the day and were almost empty when they came down.
