George Clooney testified today in front of the Senate Foreign Relations Committee, detailing his recent covert visit to the Nuba Mountains in Sudan and the atrocities being committed there. 


"We found children filled with shrapnel, including a 9-year-old boy who had both of his hands blown off," the 50-year-old actor told the audience. "It is a campaign of murder, fear and displacement and starvation."


The violence unfolding in the Nuba region comes in the wake of South Sudan's successful secession from Sudan last July. Unfortunately, the borders of the new country are still in dispute, with rich oil deposits complicating matters. 


In his testimony, Clooney slammed Sudanese President Omar al-Bashir, government official Ahmad Harun, and Defense Minister Abdelrahim Mohamed Hussein as the masterminds behind the attacks on innocent people, saying they are "proving themselves to be the greatest war criminals of this century by far."


He warned that the region could easily become another Darfur — a genocide that claimed an estimated 5 million lives. "What we're looking at is a real disaster," he said. 


In the video presented during the testimony, Clooney is shown visiting with villagers constantly under attack from air strikes. Scenes of people hiding in caves, of unexploded bombs in the earth, and of the wounded are graphic and heart-wrenching. 


“We witnessed hundreds of people running to hide in caves for their safety,” the actor said. “What you see is a constant drip of fear.”
