Earlier, Ngor told Reuters that emergency workers had struggled to retrieve the bodies because of fires caused by the strikes.

On Monday, medical charity Médecins Sans Frontières (MSF) said it had also received people wounded in the attack at Ameth Bek Hospital in Abyei town.

“So far we received over 20 patients, including several critical cases. Patients with burns were also admitted. We are providing surgical services and wound dressing, along with other emergency care,” MSF’s Christian Lindauer, the charity’s manager at the hospital, said in a statement.

Meanwhile, a drone strike near the airport in Khartoum on Monday has killed four people, including three children, the AFP news agency reports, quoting a medical source.

It also cited a military source as saying air defences in the Sudanese capital had downed several other drones launched by the RSF towards the airport.

Fighting in Kordofan, a strategic area rich in gold and oil, has intensified over the last year after the army regained control of Khartoum from the RSF.
