Hollywood actor George Clooney has donated $1m (£753,00) to combat war crimes and corruption in Africa.

The Clooney Foundation for Justice announced the gift, late on Wednesday (26 October) to the Sentry, an investigative initiative that Clooney co-founded to uncover the financial networks behind conflicts in Africa.

In a statement, Clooney said the group's focus is "to make sure war crimes don't pay."

Clooney's grant, along with others, including one from fellow actor Don Cheadle, totalled $3.45m for a fundraising campaign.

The Sentry said the money will help fund reports in the coming year on "state looting and illicit financial flows out of the war-torn countries of South Sudan, Sudan, Congo, Somalia and the Central African Republic."

Clooney and human rights activist John Prendergast founded the Sentry in 2015.
