At least seven people have been killed after part of a cliff collapsed onto leisure boats on a Brazilian lake.
Another three are missing and 32 injured following the accident in the south-east of the country.
Video circulating online shows the moment the rock detaches from the cliff face as onlookers try to yell warnings to the boats beneath.
At least one of the boats appears to have sunk, while others managed to escape.
The collapse at 11:00 local time (14:00 GMT) followed days of rain in Minas Gerais state, which had made the cliffs more susceptible to collapse, local fire officials told reporters.
“That piece will fall out,” a woman can be heard saying in a video of the accident. “Get out of there,” warns another, before the cliff collapses onto the boats.
Three vessels were hit by falling rock, Lieutenant Pedro Aihara told reporters. Out of the 32 injured, nine people were in hospital.
Divers and helicopters are searching the water for any more survivors.
Twenty people were initially reported missing, but Lt Aihara said most were accounted for after checking hospital lists.
