The latest segment of HBO’s four-part Witness series follows the French photojournalist Véronique de Viguerie in South Sudan, where thousands have been murdered, kidnapped, or displaced by Joseph Kony’s Lord’s Resistance Army.

Watch a clip from the film (which aired last night on HBO), and click-through for more from Maria Lokke on de Viguerie.

Slide Show: In the Caves of the Nuba

…Ten months on, tens of thousands of Nubans have left their villages and towns to live in caves and crevasses in the rocky mountain massifs. (I shot pictures, above, and videos, below, on a reporting trip there this week.) Khartoum’s Sukhoi and MiG jet fighters and Antonov warplanes fly daily sorties overhead, bombing frequently. Food is becoming scarce, as these people have not been able to plant their fields; there is a risk of famine with the new rainy season that begins in May. Tens of thousands more have fled south, to dank and dry brush forests. And in the Nuba Mountains, one of the oldest spots on earth, Africa’s newest war seems already to have begun.
