A 26-storey building has collapsed after being engulfed in flames in Brazil's largest city, São Paulo, killing at least one person.

More than 150 firefighters are battling the blaze which is thought to have been caused by a gas explosion.

The high-rise had been occupied by squatters. Fire authorities said they feared more people were trapped inside.

Witnesses said flames spread quickly from one of the lower floors and set an adjacent building on fire.

'Like a tsunami'

Some 50 families had moved into the building in the Largo do Paissandu area of the city after the federal police force, which had been using it, vacated it some years ago.

The São Paulo newspaper Estadão reported that makeshift living compartments in the building had been constructed from wood, aiding the spread of the blaze through the floors.

Firefighters evacuated the high-rise but as they were taking out the last of the residents the building collapsed, killing one man. One firefighter was injured, Estadão reported.

"It was a matter of seconds but we couldn't save him," firefighter Max Mena said.

"It felt like a tsunami when the building came down," a 58-year-old woman who lived on the fourth floor told Folha newspaper. "I could not take anything with me."

Deise Silva, 31, told Folha that she was asleep inside one of the rooms with her five children when she was woken by screaming.

"When people told me there was a fire, I woke up the children and ran," she said.

A nearby hotel has been evacuated. The hotel receptionist told Folha that he was alerted to the blaze by shouting.

"At first I thought it was a fight but then I heard people shouting 'get out, get out!'" he said.

The fire started at 01:20 local time (04:20 GMT) and the high-rise collapsed just 90 minutes later.

'Accident waiting to happen'

São Paulo Governor Márcio França said the building was an accident waiting to happen but that its residents had resisted leaving.

"That type of home is uninhabitable, staying there is looking for trouble," he said speaking at the site of the blaze.

Capt Marcos Palumbo of the São Paulo fire brigade said that modifications made by the residents had allowed the fire to spread more quickly.

"The lifts had been taken out and those empty air shafts formed a chimney. There was also a lot of combustible material, such as wood and paper which helped fuel the fire," he said.

Officials say the second building is currently not at risk of collapse. Firefighters have cordoned off a large area around the blaze.
