At least seven people have died and nine are seriously injured after part of a canyon collapsed onto tourist boats in Brazil.
Horrifying footage shows a tower of rock suddenly break away from the cliff edge and crash down onto several vessels on Saturday.
Three people were still missing earlier on Sunday following the incident in the south east of the country, authorities said.
Videos of the tragedy, which Metro.co.uk has chosen not to publish, show people shouting at other boats before the rock face fell away.
The main column lands directly on top of one boat, with others also thought to have been hit while trying to escape.
The collapse also sent a huge wave over the lake at Capitolio, in Minas Gerais state.
Those hurt in the accident had broken bones and one was in a serious condition in hospital with head and facial injuries.
Some 23 others were treated for light injuries.
Divers have searched the lake, which is a popular hotspot for tourists.
The region has seen heavy rainfall for two weeks, which could have loosened the rock face.
On Saturday, a dike overflowed at an iron ore mine 300 kilometers to the east, cutting off a major federal highway.
