Twenty people have reportedly died after a tree fell down at Kintampo Falls in Ghana.

They were among a number of others who were swimming in the waterfalls when a heavy storm uprooted some trees, which fell on them during a downpour. "We used chainsaws and other cutting tools to chop the tree in pieces in order to free the victims", he said.
He added that 11 more were receiving treatment, including one of the school administrators who was in charge of the trip.
Desmond Owusu Boampong, a local police commander said almost 20 people have been admitted to the hospital and are being treated.
It is reported numerous injured were taken to Kintampo Municipal hospital.
In a separate post on Twitter, John Mahama described the incident as "tragic", and called for emotional support for all the affected families.
