The most senior US diplomat at the UN condemned the Security Council for failing to act over atrocities and a growing famine in Ethiopia's Tigray region, asking "do African lives not matter?"
"The Security Council's failings on Tigray are unacceptable," Linda Thomas-Greenfield, ambassador to the UN, said at a virtual event organised by the US and the European Union.
She said it was "time for the Ethiopian government to respond responsibly to requests for humanitarian access".
Thomas-Greenfield made the comments as the UN and aid agencies said more than 350,000 people faced extreme food shortages in Tigray, renewing memories of a famine that left a million people dead in the 1980s.
That is the largest number of people classified at 5 on the Integrated Food Security Phase Classification (IPC) famine scale - the highest level possible - in a single country for a decade.
