MARIANA, Brazil (AFP) - A dam burst on Thursday (Nov 6) at a mining waste site in Brazil, killing at least 17 people and injuring more than 50, a fire chief said.
"The number of missing is going to surpass 40 but that is not official," said Adao Severino Junior, fire chief in the city of Mariana in south-eastern Minas Gerais state.
The village of Bento Rodrigues near the dam is practically buried in mud, the fire chief said.
"The situation is grim. It is dark. There is a lot of mud," Severino said.
Rescue operations will continue through the night, he added.
