South Sudan - President Dismisses Cabinet and Vice President - NYTimes.com President Salva Kiir dismissed his entire cabinet and his vice president on Tuesday and suspended his top negotiator at talks to defuse tensions with Sudan, state news media said. State television cited a presidential decree saying the ministries would be run for now by their under secretaries. Mr. Kiir has been facing dissent over an economic crisis, largely the result of disputes with Sudan that have prevented it from exporting crude oil, and endemic corruption. Vice President Riek Machar recently hinted that he might challenge Mr. Kiir for the party leadership before the 2015 elections, and Mr. Kiir stripped him of some his duties in April in what seemed to be a move to lower his profile. No further details were immediately available.
