Blazing high-rise collapses in Sao Paulo

An abandoned high-rise building occupied by squatters in downtown Sao Paulo caught fire and collapsed Tuesday, sending chunks of fiery debris crashing into neighboring buildings and surrounding streets.

Firefighters said at least one person had been killed in the collapse and that there could be more.

The building, a former federal police headquarter, caught fire around 1:30am local time. Firefighters set up a perimeter and worked to evacuate people.
