he added on the social media platform X<\/a>.<\/p>\nSouth Sudan’s government has not yet commented on the deployment.<\/p>\n
Concern about the security situation in South Sudan has been mounting, with the US on Saturday ordering the evacuation of all its non-emergency staff from the country.<\/p>\n
Last week, the deputy chief of the army and two ministers – all allies of Machar – were arrested by the security forces, which an opposition spokesman called a “grave violation” of the peace deal.<\/p>\n
One of the ministers has since been released.<\/p>\n
The arrests followed clashes in the Upper Nile state between government forces and a militia known as the White Army.<\/p>\n
It had fought alongside Machar during the civil war that broke out in 2013 following a power struggle between him and Kiir.<\/p>\n
It led to heavy fighting in Juba, with Kiir accusing Machar of plotting a coup.<\/p>\n
Machar denied the allegation, but South Sudan then plunged into a civil war that killed more than 400,000 people.<\/p>\n
A 2018 power-sharing agreement between the two stopped the fighting, but key elements of the deal have not been implemented \u2013 including a new constitution, an election and the reunification of armed groups into a single army.<\/p>\n
