Brazilian President Jair Bolsonaro and other officials called the incident a “tragedy.”

Five people have been arrested in connection with the collapse — three were employees with Vale, BBC News reported.

The cause of the burst is still being investigated.

BBC News also reported that an alarm system, installed in an effort to notify residents in case of any risks associated with the mine, was not sounded.

Tuesday marked the fifth day of searching for bodies or survivors.
