 The United Nations on Tuesday denied claims that refugee camps in Sudan were being used by Ethiopian rebels as a both-hole. Ethiopian officials said fighters had been caught with refugee ID cards. Tens of thousands of Ethiopian refugees have streamed across the border into Sudan since war broke out 10 months ago in Ethiopia. Prime Minister Abiy Ahmed sent troops into Tigray to topple the regional ruling party, the Tigray People's Liberation Front. He says the move came in response to TPLF attacks on army camps. Although the 2019 Nobel Peace Prize winner vowed a swift victory, the war has dragged on and it has spread into neighboring Afar and Amhara regions.
