Sudanese civilians flee as ceasefire attempts fail.

A new ceasefire attempt between Sudanese troops and paramilitary forces in Khartoum has failed, leading to concerns over food and medical supplies. The conflict has shut down the UN's work in the country, with hospitals and aid workers targeted by gunmen. At least 270 people have died and 2,600 have been injured. Foreign powers have pressed for a ceasefire to allow for evacuations and the delivery of supplies, but truces announced by both sides have not held. The conflict has dashed hopes for progress towards democracy in Sudan and risks drawing in its neighbours.
