Ante Up For Africa, a non-profit organization founded by actor Don Cheadle and poker player Annie Duke, announced a $600,000 donation to three Darfur-related charities.

The goal is to provide relief for the people affected by the violence in that area, according to a press release. Proceeds were raised through poker tournaments, which have raised more than $2.5 million for Darfur charities since launching in 2007.

"When we started Ante Up, we had no idea that so many people would respond and participate to combat the devastation in Darfur," said Annie Duke. "It reaffirms our belief in humanity and drives us to do more for people in need."

Darfur, located in western Sudan, is experiencing a humanitarian crisis which has seen hundreds of thousands killed and millions driven from their homes.

The release says Ante Up for Africa will donate:

$300,000 to Darfur Peace & Development Organization (DPDO), a Darfuri-led non-governmental organization that continues to provide aid to those in need in Darfur and the refugee camps.

$150,000 to Refugees International, an organization that advocates for lifesaving assistance and protection for displaced people.

$150,000 to the Enough Project, a project of the Center for American Progress that is working to build a permanent constituency to prevent genocide and crimes against humanity.

The Ante Up for Africa tournament airs at 8 tonight on ESPN.
