The Sudan People's Liberation Army soldiers stand at attention at a containment site outside Juba on April 14, 2016. The soldiers at the site are the Tiger Battalion of the presidential guard consisting of a total of 700 soldiers. The site is about 30 km outside of Juba as per the transitional security arrangements of the South Sudan peace agreement. The demilitarisation of Juba is an important part of the peace agreement of the cessation of hostilities signed in August 2015 and seen as a way forward to forming the transitional government of national unity. This has also been a sticking point before the return of Rebel leader Riek Machar who is due to be sworn in as the country's Vice President.
