A 26 storey residential building has collapsed in Brazils larget city Sao Paulo, killing atleast one person. More than 150 firefighters are still battling a blaze thought to have been caused by a gas-leak explosion. The high-rise building was being occupied by squatters who refused to leave even by the Governor's request. An estimated 50 families were living in the building in makeshift rooms and apartments. The excess of flammable makeshift materials is believed to have contributed the fire's rapid spreading.
