Aleast 18 people, mainly high school students, have died after a large tree fell on them at a popular waterfall spot in Kintampo, Ghana, police say.
The students were swimming during a storm when the freak accident happened, local police chief Owusu Boampong said. 22 others were injured and are being treated at local hospitals.
Rescue teams used chainsaws to cut through the fallen tree and free those trapped underneath. An eyewitness said most of those involved were students of the Wenchi Senior High School, but that there were also tourists.
