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

The World Health Organization (WHO) has warned of a "high risk of biological hazard" in Sudan's capital, Khartoum, after one of the warring parties seized a laboratory holding measles and cholera pathogens and other hazardous materials. The WHO's representative in the country said technicians were unable to gain access to 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.
