Residents in Khartoum, which is controlled by the army, told the AFP news agency that they were woken overnight by the sound of drones and explosions. The blasts appeared to take place near a military base and a power station in the early hours of Friday morning, the residents said. The RSF has not addressed these accounts, but Sudan's military-led government said it would be wary of agreeing to a truce as the group did not "respect" ceasefires.

The two sides have been embroiled in a civil war that has killed at least 150,000 people and forced 12 million others from their homes since it erupted in April 2023. This week a UN-backed global hunger monitor confirmed that famine conditions were spreading in conflict zones. On Friday, drones were heard not only in Khartoum, but also 300km (186 miles) north of the city, in the military-controlled town of Atbara. "Anti-aircraft defences shot them down, but I saw fires breaking out and heard sounds of explosions in the east of the city," a resident there told AFP. The day before, the RSF announced it had agreed to a humanitarian truce proposed by the US, the United Arab Emirates (UAE), Saudi Arabia and Egypt.

The four countries put forward the plan in September - and said it should be followed by a permanent ceasefire and a transition to civilian rule. At the time the Sudanese government rejected "foreign interference" and any attempts that equated it with a "racist terrorist militia that relies on foreign mercenaries". It is not clear if the proposal has been modified since then. (BBC)
