“Every country must accept the return of its citizens in a timely manner when another country, including the United States, seeks to remove them,” Rubio said in a statement, adding that “South Sudan’s transitional government has failed to fully respect this principle”. Besides revoking visas, Rubio said the US would “prevent further issuance to prevent entry into the United States by South Sudanese passport holders”. South Sudan’s political landscape is fragile and recent violence between government troops and armed opposition groups has escalated tensions.  Last week, United Nations Secretary-General Antonio Guterres urged regional and international leaders to prevent South Sudan from falling “over the abyss” into another civil war.
