Fighting intensified in Sudan’s war-ravaged province of Darfur during a fragile three-day truce between the country’s battling top generals, killing an estimated dozens of people, residents said on Thursday.

The truce eased fighting in the country’s capital, creating a lull that allowed foreign governments to evacuate thousands of their nationals. Tens of thousands of Sudanese traveled to their country’s land borders with Egypt, Chad and Ethiopia, and to a port city on the country’s Red Sea.
