B: Tigray is a region of Ethiopia. The Tigray People's Liberation Front is a political party with a military wing from the region which dominated Ethiopian national politics for decades. The TPLF had been in conflict with the federal Ethiopian government over proposed political reforms, and the postponement of the federal election. In response, Tigray held its own elections, and the Tigrayan and federal governments each deemed the other illegitimate. Military conflict began in Tigray in November 2020 after Ethiopia's Prime Minister Abiy Ahmed sent troops to topple the Tigray People's Liberation Front, which dominated national politics before he took office in 2018.
This troop movement was allegedly in response to TPLF attacks on federal army camps. Government forces drove the TPLF from Tigray's cities and towns, but the rebels retook most of the region, including its capital, Mekele, by late June.
The war has soured relations between Ethiopia and Western powers, including the United States, long a critical ally.
