US 'very engaged' in Sudan ceasefire talks: White House

"The United States is actively engaged in efforts to bring about a peaceful resolution to the terrible conflict in Sudan," White House Press Secretary Karoline Leavitt tells reporters at the White House. The war, which has killed tens of thousands of people and displaced millions more over the past two years, has spread to new areas of Sudan in recent days, sparking fears of an even greater humanitarian catastrophe. No details of the US truce proposal have been made public. SOUNDBITE
