George Clooney has donated $1 million to help fight war crimes in Africa.

The Hollywood actor made the generous donation to the Sentry, an investigative group that strives to put a stop to war crimes and has recently launched its Make Criminals Pay campaign, which is focused on bringing war-profiting networks to justice.

In a statement, George - who is also the co-founder of the charity - said: ''Our focus is to make sure that war crimes don't pay. We want to make it more difficult for those willing to kill en masse to secure their political and economic objectives.

''When we're able to go after the warlords' wallets and bankrupt those who choose the bullet over the ballot, suddenly the incentives are for peace, not war; transparency, not corruption.''

George, 56, founded the Sentry in 2015 with the help of John Prendergast, a human rights activist.

Meanwhile, George recently admitted he is ''scared to death'' he will ''break'' his children.

The acclaimed actor said he is terrified when he holds his four-month-old twins Ella and Alexander - who he has with his wife Amal Clooney - as he fears he will hurt them because they are ''so little'' and fragile.

He shared: ''Listen, I'm scared to death, it's terrifying. You're afraid of breaking them. They're so little.''

Despite this, the twins have recently been introduced to solid food, and George joked about the way in which his kids process their meals.

George - who married Amal in 2014 - quipped: ''We introduced the children to solid food on Friday. How that goes in as a carrot and how that comes out the way it comes out is shocking. I don't know what's going from here to here. What happens?''
