Nine people have died and up to 300 are missing after a dam collapsed at an iron ore dam in Brazil.
The break caused a flow of muddy sludge to bury the dam’s cafeteria where hundreds of workers were eating lunch.
Local television channel TV Record showed a firefighters’ helicopter hovering inches off the ground as it pulled people covered in mud out of the sludge.
Romeu Zema, Governor of the state of Minas Gerais, said there was little chance of finding people alive.
Photos showed the rooftops of structures poking above an extensive field of the mud, which also cut off roads.
Brazilian mining company Vale SA said the flow reached the community of Vila Ferteco and an administrative office, where employees were present, which “indicated the possibility of victims.”
President Jair Bolsonaro sent a tweet saying he lamented the incident and was sending the three cabinet ministers to the area.
Another dam administered by Vale and Australian mining company BHP Billiton collapsed in Mariana, Minas Gerais, in 2015, resulting in 19 deaths and displacing hundreds from their homes.
It is considered the worst environmental disaster in Brazilian history, with 60 million cubic metres of waste flooding rivers and eventually reaching the Atlantic Ocean.
