Diplomats and aid officials from around the world are meeting in London to address the humanitarian crisis in Sudan, which has killed tens of thousands of people and displaced 14 million. The conference aims to provide relief and aid to those affected by the 2-year-old war, but does not include representatives from the Sudanese government or the rival paramilitary. The war has led to famine and pushed millions of people from their homes, with half of Sudan's population facing extreme hunger. The U.S. is expected to be represented at the conference despite recent cuts to foreign aid.
