Pope Francis wraps up an emotional visit to Democratic Republic of Congo on Friday and heads to neighbouring South Sudan, another nation struggling to overcome decades of conflict and grinding poverty.
The 86-year-old pontiff, on his third visit to sub-Saharan Africa since his papacy began in 2013, was given a rapturous welcome by huge crowds in the Congolese capital Kinshasa but also confronted the reality of war, poverty and hunger.
On Wednesday, he heard harrowing stories from victims of conflict in eastern Congo who had witnessed the killings of close relatives and been subjected to sexual slavery, amputation and forced cannibalism.
The pope condemned the atrocities as war crimes and appealed to all parties, internal and external, who orchestrate war in Congo to plunder the country's vast mineral resources to stop getting rich with "money stained with blood".
Eastern Congo has been plagued for decades by conflict driven in part by the struggle for control of deposits of diamonds, gold and other precious metals between the government, rebels and foreign invaders. The spillover and long fallout from neighbouring Rwanda's 1994 genocide have also fuelled violence.

Francis returned again and again to the theme of conflict fuelled by "the poison of greed", saying the Congolese people and the wider world should realise that people were more precious than the minerals in the earth beneath them.
After a meeting with Congolese bishops in Kinshasa on Friday morning and a farewell ceremony at the airport, his plane is scheduled to take off at 0940 GMT, heading for Juba, the capital of South Sudan, where it is expected to land around 1300 GMT.
The pope will be joined for the whole of his visit to South Sudan by Archbishop of Canterbury Justin Welby, leader of the global Anglican Communion, and by the Moderator of the General Assembly of the Church of Scotland, Iain Greenshields.
It is the first joint foreign trip by the three Christian leaders, who have called it a "pilgrimage of peace".
South Sudan broke away from Sudan to become independent in 2011 after decades of north-south conflict, but civil war erupted in 2013. Despite a 2018 peace deal between the two main antagonists, violence and hunger still plague the country.
Francis has wanted to visit the predominantly Christian country for years but each time planning for a trip began it had to be postponed because of instability on the ground.
In one of the most remarkable gestures of his papacy, Francis knelt to kiss the feet of South Sudan's previously warring leaders during a meeting at the Vatican in April 2019, urging them not to return to civil war.
