WHO warns of "huge biological risk" in Sudan amid fighting and lab seizure.

Fighters in Sudan have seized control of the National Public Health Laboratory in Khartoum, which houses samples of polio, cholera, and measles, creating a huge biological risk for the country. The lab seizure occurred amid fighting between the Sudanese Armed Forces and the Rapid Support Forces, which has resulted in hundreds of deaths and thousands of injuries. The WHO has warned of an acute shortage of food, medicine, water, and fuel in the country, and the International Committee for the Red Cross has called for a long-lasting solution to protect civilians. The US has evacuated embassy staff, but up to 16,000 American citizens remain in the country.
