The death toll climbed to 14 from the collapse of three buildings in central Rio de Janeiro, officials confirmed Friday, but the cause of the accident still remained unclear. Around 20 people were still missing from Wednesday's collapse of three adjacent office buildings - 20, 10 and four storeys high - in the heart of the city. Civil Defence commander Sergio Simoes has said there is virtually no chance of finding survivors, according to a report of DPA.
