South Sudan on Sunday marked its sixth independence anniversary in muted fashion, with no official celebration as the world's newest nation reels from a brutal and destructive ongoing civil war.
As of March 2017, a United Nations Report accused the government of South Sudan of continuing to spend its oil revenue on the purchase of arms.
Kiir said he pledged his "100 percent commitment" to ensuring Machar's security while in Juba.
There is no precise official toll of how many died, either in the recent fighting in Juba or in the wider war that began in December 2013.
Friday's violence in South Sudan is yet another blow to a shaky peace deal that has so far failed to end the civil war that broke out in December 2013.
The gunfire began outside the presidential compound and soon spread through the city of Juba.
The violence echoed the skirmish between soldiers in Juba in 2013 that sparked the country's civil war in which tens of thousands of people were killed.
