Fire Brings Down The Building

Just like with the WTC, explosives not required to bring down the building:

SÃO PAULO, Brazil — A high-rise tower in São Paulo, Brazil, collapsed early Tuesday after a fire raged through the building and spread to two other structures nearby. At least one person was believed to have died.

The collapsed building, which reached more than 20 stories high, was a former federal police facility that was inhabited by about 150 squatters, city officials said, but it appeared that the vast majority of them escaped the blaze.
