A horrifying tragedy was captured on video in Brazil.
Boaters were enjoying a popular tourist attraction when the unthinkable happened.
A rockface started to collapse, with a massive chunk of the cliff separating from the wall and crushing several boats.
The video is mind-boggling to watch.
Some boats in the nearby area started to see the rocks crumbling.
You can hear them screaming warnings to other boats closer to the rock face to move out of the way.
One boat heeded the warning, while another boat never moved, taking the brunt force of the cliff.
The accident happened at the lake at Capitolio, in Minas Gerais state, in southeastern Brazil…
Authorities have stated that at least seven people are known to be dead.
Three were still missing, and more than two dozen were injured.
Rovilson Teixeira stated, “We are all stunned, nobody knows how many victims, but I can already tell you that there were not one or two deaths, but many deaths.
“There are a lot of hurt people.
“The region is full of ambulances that have come from other areas to pick up the victims, but no one yet realizes the scale of the tragedy here.”
Of those taken to the hospital, 23 are believed only to have suffered minor injuries.
At least one person is currently listed in critical condition of those remaining.
