At least 40 people in Sudan have been killed in a drone strike that targeted a funeral that was taking place outside the army-held city of el-Obeid in North Kordofan state, officials and activists say.

They blamed the paramilitary Rapid Support Forces (RSF) for the attack on al-Luweib village as mourners had gathered in a tent. The RSF has not yet commented.

Many reportedly died before getting to hospital in el-Obeid, a strategic city that connects the capital, Khartoum, to the western region of Darfur.

Fighting has intensified in this oil-rich Kordofan area and around 20,000 people fled to el-Obeid last week after the RSF captured Bara town, located 30km (18 miles) north of the city.

The town fell at the same time as the city of el-Fasher, which had been the army's last stronghold in Darfur.

Since then, reports have surfaced detailing mass killings, sexual violence, abductions, and widespread looting in el-Fasher by RSF fighters.

The UN has reported instances of summary executions of civilians by RSF forces in Bara.

Such atrocities could amount to war crimes and crimes against humanity, the International Criminal Court (ICC) has warned.

The ICC has issued a statement while the RSF leader vowed to investigate violations, though the group denies widespread allegations claiming that the killings in el-Fasher are ethnically motivated.

The global group of food security experts confirmed that el-Fasher residents are facing famine due to the RSF's prolonged siege.

UN Chief António Guterres has called for an immediate halt to violence, warning of a rapidly worsening humanitarian crisis.

The horrifying crisis in Sudan... is spiraling out of control, he emphasized during a recent summit.

Authorities are assessing a US proposal for a truce amidst ongoing efforts by Washington and other states to broker a ceasefire in the conflict.

Since civil war erupted between the army and RSF in April 2023, over 150,000 people have died, and approximately 12 million have fled their homes in what the UN deems the world's largest humanitarian crisis.
