Uganda's President Yoweri Kaguta Museveni (left) interacts with his South Sudan counterpart Salva Kiir shortly on arrival to attend the 4th National Liberation Council Meeting of the Sudan People's Liberation Movement in Juba on Thursday May 3, 2018.
Uganda has moved to rectify the legal gaps in deploying troops to Juba, in what it argues is a move to protect President Salva Kiir, an ally of Kampala.
That deployment had been clothed in confusion, however, after heads of the military and the ministry of defence contradicted each other. On Friday, officials said Uganda was responding to an SOS from President Kiir to have backup security.
