The US is revoking all visas for South Sudanese passport holders due to the country's failure to accept repatriated citizens. Secretary of State Marco Rubio emphasized the need for South Sudan to comply with repatriation principles. This decision comes amid fears of a potential return to civil war in South Sudan, which has struggled with governance and conflict since its independence in 2011. The situation has worsened with the recent escalation of violence and the collapse of a power-sharing agreement between leaders.
