Tower block collapses in São Paulo after fire

A 26-storey building has collapsed after a massive fire in the Brazilian city of São Paulo.

More than 170 firefighters are at the scene, along with a civil defence response team and the army.

One person has been confirmed dead and several more are feared dead after screams for help were heard from the top floor of the building.

The block was occupied by rough sleepers and a number of people are believed to be trapped in the rubble.

It is not clear how many people were in the building at the time but 50 families are registered as living there, according to local media.

The blaze is understood to have started on the third floor and then spread rapidly to the levels above.
