At least 22 people were still missing yesterday after rescuers recovered four bodies from the rubble of three buildings that collapsed in downtown Rio de Janeiro, Mayor Eduardo Paes said.
Paes told a news conference six others had been pulled alive from the rubble. The buildings, one 20 floors high, collapsed in a cloud of dust behind the city's 100-year-old Belle Epoque-style Municipal Theatre.
They housed offices that had mostly closed for the day. Paes said the cause of the collapse could have been a structural failure as a result of building work in one of the buildings.
