In Ghana (northwest Africa) — at least 20 young people, most of them local high-school and college students, died when a large tree fell on top of them while they were swimming at the bottom of a waterfall — Kintampo Waterfalls. It is a popular tourist destination.
The students and some tourists were swimming there while there was a storm with strong winds. Some of the trees fell on top of the students, hitting them and pinning them under the water.
It seems like 18 died at the scene while 2 more died at the hospital. Terrible.
We can learn a lesson that we should be careful about swimming in areas with large trees if it is very windy.
