South Sudan's First Vice-President Riek Machar has been charged with murder, treason, and crimes against humanity in a move that some fear could reignite the country's civil war.
Justice Minister Joseph Geng Akech stated that the charges against Machar relate to an attack in March by a militia allegedly linked to the vice-president.
The roads leading to his house in the capital, Juba, have been blocked by tanks and soldiers.
Forces loyal to Machar fought a five-year civil war against those backing President Salva Kiir until a 2018 peace deal.
He has been under house arrest since March, with the UN, African Union, and neighbouring countries all calling for calm.
The 2018 peace deal ended a conflict that had killed nearly 400,000 people; however, the relationship between Machar and Kiir has become increasingly strained amid ethnic tensions and sporadic violence.
