Three Buildings Collapse in Rio

Three buildings collapsed in Rio, including one that was 20 stories high. Officials said three bodies have been recovered, but up to 16 people still remain missing. The cause of the collapse is unclear, but witnesses report an explosion and a strong smell of gas. One witness told Reuters, "It was like an earthquake. First some pieces of the buildings started to fall down. People started to run. And then it all fell down at once." Three months ago, a suspected gas explosion at a restaurant left three people dead.
