IN THE NUBA MOUNTAINS, Sudan

AS Sudan tries to bomb and starve the Nuba people into submission, it faces an unlikely antagonist: an American man from Florida who married a Nuban woman, gets by on local foods like locusts, and is fighting mortars with video cameras.

Ryan Boyette, 30, is trying to get President Obama to do more to intervene to stop the bombing and avert a famine. He is risking his life to collect video of atrocities that the world frankly doesn’t seem to be terribly interested in.

It was Boyette who smuggled me into the Nuba Mountains, driving his Toyota Land Cruiser on a rutted dirt track from South Sudan, at one point just a couple of miles from Sudanese military lines. He has set up a network of local citizen journalists who use small cameras to document atrocities and starvation in hopes of making the world care enough to intervene.
