Actor and human rights activist George Clooney made a quiet visit to a volatile border region between Sudan and South Sudan last week ahead of testimony he's giving before a U.S. Senate committee today.
Clooney made the dangerous crossing from South Sudan into Sudan's Nuba Mountains region according to a spokesman for the anti-genocide group the Enough Project.
Clooney saw burned-out villages and met with residents forced to seek shelter in caves because of aerial attacks by Sudan's military.
Clooney travelled to what is now known as South Sudan in January 2011 as the region cast votes to secede from Sudan.
After that visit, Clooney helped found the Satellite Sentinel Project, which uses satellite imagery to track military movements and attacks in the hopes of bringing attention to and potentially heading off hostilities.
On his most recent visit Clooney, met South Sudan President Salva Kiir and the country's defence minister.
