Eyewitnesses describe the scene as the buildings collapsed
The bodies of three people have been recovered in Brazil by rescue workers searching through rubble after the collapse of two high-rise office buildings in Rio de Janeiro.
Officials say that at least 19 people remain missing, while a further six were taken to hospital.
City Mayor Eduardo Paes said current investigations were focusing on structural problems.
The buildings, one of which was 20 storeys, collapsed late on Wednesday.
He discounted speculation that a gas explosion could have caused the collapse.
The buildings, which were respectively 10 and 20 storeys high and were located near the Municipal Theatre and the headquarters of oil giant Petrobras, crushed a four-storey construction site on their way down.
Dozens of emergency workers attended the scene and police cordoned off the area.
Electricity to the street has been cut off for safety reasons.
Concerns have been raised about the state of Rio de Janeiro’s infrastructure as Brazil prepares to host football’s World Cup in 2014 and the Olympic Games two years later.
