The World Health Organization is warning of an unparalleled health crisis in Ethiopia’s Tigray region, where 6 million people have been sealed off from the outside world for 500 days as separatists battle government forces. WHO Director-General Tedros Adhanom Ghebreyesus — who is from Tigray — said Wednesday about three-quarters of health facilities in the region have been damaged or destroyed by fighting.

Tedros Adhanom Ghebreyesus: “There is almost no fuel, no cash and no communications. No food aid has been delivered since the middle of December. Eighty-three percent of the population is food insecure. Our partners are running out of what little food they have and the fuel to transport it.”
