WHO warns of bio-hazard risk in Sudan after lab seizure.

The World Health Organization has warned of a "high risk of biological hazard" in Khartoum, Sudan, after a laboratory holding measles and cholera pathogens and other hazardous materials was seized by one of the warring parties. The WHO's Nima Saeed Abid said technicians were unable to access the National Public Health Laboratory to secure the materials. Fighting between the Sudanese armed forces and Rapid Support Forces (RSF) paramilitaries has killed at least 459 people and injured 4,072, according to the WHO's latest figures.
