The information about the hospital comes two days after the UN warned of war crimes in the city, which the RSF (Rapid Support Forces) said this weekend had taken full control of.
Forces allied with the Sudanese military accuse RSF of killing over 2,000 unarmed civilians in two days in the city.
The WHO also warned at the time that the only functioning hospital in the city had been attacked, but without the new information that over 460 patients and their relatives had been killed there. It is not clear where the WHO's information comes from.
There is great concern for the situation of the civilian population and on Wednesday the EU condemned RSF's "brutality".
"Targeting civilians based on their ethnicity underscores the brutality of the Rapid Support Force," EU foreign policy chief Kaja Kallas wrote in a statement.
"Humanitarian organizations must be granted immediate, safe and unconditional access to all those in need. Civilians who wish to leave the city must be allowed to do so safely," the statement, which is also signed by Hadja Lahbib, EU Commissioner for Humanitarian Aid and Crisis Management, further states.
The United Nations World Food Programme (WFP) says two staff members in Sudan have been ordered by the State Department to leave the country without explanation, as “more than 24 million people face acute food insecurity and communities are facing famine,” the WFP said.
The paramilitary force RSF has been at war with the country's military since April 2023.
