South Sudan's army said it had recaptured a key town in Upper Nile state that it lost to an ethnic Nuer militia in March in clashes which led to the arrest of First Vice President Riek Machar and a spiralling political crisis.
President Salva Kiir has served in an uneasy power-sharing government with Machar since a 2018 peace deal ended a civil war between fighters loyal to the two men which killed hundreds of thousands of people.
