A high-rise building in downtown Sao Paulo was engulfed in flames and smoke early on Tuesday, in a huge fire that caused the 26-storey tower to collapse. At least 150 firefighters were on the scene working to extinguish the blaze, which is thought to have been caused by a gas explosion. At least one person is said to have died in the incident, with three others reportedly missing... Еще. Firefighters have cordoned off the area around the fire. The building reportedly was a former Federal Police facility occupied by squatters.
