Nobel Peace Prize laureate Abiy Ahmed says he'll bury his government's enemies with their blood. The Ethiopian prime minister's words come on the first anniversary of the internal conflict with Tigray rebels. With at least 2 million people displaced by fighting and thousands already killed, the US is sending an envoy to urge a peaceful solution. Meanwhile, the UN has published a report citing allegations of war crimes on both sides. Is there any hope for de-escalation?
