Explosions have been heard near the Sudanese capital of Khartoum, a day after the paramilitary Rapid Support Forces (RSF) said it would agree to a humanitarian ceasefire.
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.
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. But during a press conference on Friday, Sudan's ambassador to South Africa said it was too early for his country to agree to the plan.
Eyeing the dynamics of the recent territorial gains by the RSF and the lack of respect for previous truces, the ambassador expressed deep skepticism about the sincerity of any upcoming ceasefire efforts.
