“A 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,” The Associated Press reported.

In the video, firefighters are seen spraying water with their hoses on the smoldering rubble as they search for missing people.

“There is no official information on the number of missing persons or on the identity of the one confirmed victim,” CNN reported.
