Pope Francis is due to wind up his trip to the Democratic Republic of Congo and arrive in South Sudan on Friday on a three-day visit to promote peace and reconciliation in a country still bearing the scars of civil war.
Francis is scheduled to land in Juba at 3pm (1300 GMT), in the first visit to South Sudan by a pope since the predominantly Christian nation gained independence from Muslim-majority Sudan in 2011 after decades of bloody struggle.
Peace has eluded South Sudan in statehood too, with a five-year civil war leaving 380,000 people dead, four million displaced, and the young country deeply impoverished.
Meet conflict victims
The 86-year-old is expected to meet victims of the conflict, as well as the country's political and church leaders, between prayers and an outdoor mass that is expected to draw large crowds.
The visit — Francis's fifth to Africa — was initially scheduled for 2022 but had to be postponed because of the pope's problems with his knee.
The affliction has made him dependent on a wheelchair, and seen a paring-back of parts of the itinerary in both countries.
He will be joined in South Sudan by the Archbishop of Canterbury and the Moderator of the General Assembly of the Church of Scotland in what is being billed as a "pilgrimage for peace".
Hope for peace
The visit has been long anticipated in a devout country of 12 million where the church is a deeply respected institution with a long history of peace-building.
Francis promised in 2019 to travel to South Sudan when he hosted the country's two warring leaders at a Vatican retreat and asked them to respect a hard-fought ceasefire for their people.
In scenes that reverberated in South Sudan, where 60 percent of the people are Christian, the Argentine knelt and kissed the feet of two foes whose respective armies had been accused of horrific atrocities.
But four years later, South Sudan remains mired in intractable conflict and hopes are pinned on Francis encouraging much-needed unity in a nation riven with ethnic and political division.
Suffered a lot
"We have suffered a lot. Now, we want to achieve peace," said Robert Michael, a 36-year-old businessman, beneath one of many towering billboards in Juba welcoming the Pope.
Friday has been declared a public holiday and officials have encouraged South Sudanese to turn out in droves, but have not offered an estimate of how many are expected to attend the pope's appearances.
Roads in the capital have been tarmacked for the occasion, and security officials said Wednesday that an additional 5,000 police and soldiers would be on the streets.
Landmark DR Congo visit
The visit follows a three-day stop in Kinshasa, the capital of neighbouring DR Congo, where a bloody conflict in the mineral-rich east was high on the pope's agenda.
It was the first time since 1985 that a pope has visited the DRC, a vast but deeply troubled country the size of continental western Europe, which has Africa's biggest Catholic following.
Francis slammed "brutal atrocities" after hearing harrowing accounts from eastern Congo, including testimony from victims of sexual violence and mutilation at the hands of militias.
Mercy from God
Francis called for mercy from God.
"May he convert the hearts of those who carry out brutal atrocities, which bring shame upon all humanity," the pope said.
He added that the conflict was driven by greed for resources at the expense of innocent victims, and denounced "economic colonialism" in the turbulent region.
Francis also hosted a mega-mass at Kinshasa's airport and implored young Congolese to shun corruption, at a packed stadium event attended by tens of thousands.
About 40 percent of DRC's more than 100 million people are Catholic, according to estimates.
