Actor George Clooney and his father arrested at a protest outside the Sudanese Embassy in Washington.

The protesters accuse Sudan’s president, Omar al-Bashir, of provoking a humanitarian crisis and blocking food and aid from entering the Nuba Mountains in the county’s border region with South Sudan.

Clooney, along with his father, Nick and others, including Democratic U.S. Rep. Jim Moran of Virginia and civil rights leader Ben Jealous, were arrested after the police warned them three times not to cross a police line outside the embassy. They were handcuffed and placed into a U.S. Secret Service van.

He said earlier that he hopes to draw more attention to the issue and that if action is not taken in the next three to four months “we’re going to have a real humanitarian disaster.”
