An attack on the main hospital in the western Sudanese town of Al-Fashir on Friday killed nine people and wounded 20, including patients and their families, the head of the World Health Organization said.
In a posting on X Saturday, WHO Director General Tedros Adhanom Ghebreyesus added that "continued attacks on health across Sudan are deplorable."
"We urge for the protection of all patients and health professionals, and for all attacks on and around health facilities to stop," he said.
Since April 2023, Sudan has been ravaged by a war between two generals, army chief Abdel Fattah al-Burhan and his former deputy Mohamed Hamdan Dagalo, head of the paramilitary Rapid Support Forces, or RSF.
The war has left tens of thousands of civilians dead, displaced more than 11 million people, and plunged the East African country into the worst humanitarian crisis in recent years.
Al-Fashir, the capital of North Darfur, has been besieged since May by the RSF, which has blocked trade and aid deliveries to the region.
