Gunfire and explosions could be heard in Khartoum for a 20th straight day on Thursday after the latest ceasefire expired on Wednesday. Earlier, UN chief Antonio Guterres acknowledged the international community had "failed" Sudan. The UN refugee agency also reiterated calls for donors to help support the thousands of civilians who have fled the conflict.
The regular army said it was ready to abide by a new seven-day truce agreed with South Sudanese mediators, but there was no word from its rivals in the paramilitary Rapid Support Forces (RSF).
