The African Union has scheduled peace talks for next week in South Africa over the worsening crisis in Ethiopia’s Tigray conflict. On Wednesday, the World Health Organization’s Tedros Adhanom Ghebreyesus warned time is running out to resolve the war, which broke out nearly two years ago.

Tedros Adhanom Ghebreyesus: “This is a health crisis for 6 million people, and the world is not paying enough attention. I urge the international community and the media to give this crisis the attention it deserves. There is a very narrow window now to prevent genocide.”

Thousands have been killed in the brutal conflict; one analyst estimates the death toll to be as high as 800,000 people. Millions have also been displaced, and hundreds of thousands are facing famine. An investigation last year found that all sides fighting in the war had committed violations that might amount to war crimes.
