South Sudan rebel leader Machar returns to Juba after two years

South Sudan rebel leader Riek Machar returned to the capital Juba for the first time in more than two years on Wednesday to take part in a peace ceremony, an AFP reporter said.

Machar, who under the terms of the peace deal is to be reinstated as vice president, had not set foot in the city since he fled in July 2016 under a hail of gunfire when an earlier peace accord collapsed.

The rebel chief arrived at Juba airport at 9:30am (0630 GMT) and was welcomed by President Salva Kiir, Machar's former ally turned bitter enemy.

The two are to join regional leaders at the ceremony later Wednesday to publicly welcome the most recent peace agreement, signed in the Ethiopian capital Addis Ababa in September.

It was not immediately clear if Machar would remain in Juba after the ceremony, as his aides have expressed concerns over his safety in the city.

'Here for peace'
A previous planned homecoming for Machar was put off by wrangling over how many bodyguards he could bring with him and what weapons they would carry.

Lam Paul Gabriel, a spokesman for Machar's SPLM-IO rebel group, had said on Tuesday that he would be accompanied by around 30 political figures.

"We are worried for his security in Juba, but the truth is here: we are for peace, and what we are trying to do is build trust. So that is why he is able to leave his forces behind and just go with politicians," Gabriel said.

Thousands of people had already gathered for the ceremony at the John Garang Mausoleum, built in honour of the independence hero who was killed in a helicopter crash in 2005.

Among regional leaders in Juba for the ceremony were Sudanese President Omar al-Bashir, Ethiopia's newly appointed President Sahle-Work Zewde and Somalia's head of state Mohamed Abdullahi Mohamed.

Ugandan President Yoweri Museveni was also expected to attend.

Machar fled Juba in July 2016 after fierce fighting erupted between government forces and his rebels, leaving several hundred people dead.

He first headed on foot to the Democratic Republic of Congo before finally going into exile in South Africa.

Deep humanitarian crisis
South Sudan's civil war erupted when Kiir, a member of the Dinka tribe, accused his then deputy Machar, a Nuer, of plotting a coup.

The conflict split the country along ethnic lines and has seen mass rape, the forced recruitment of child soldiers and attacks on civilians.

It has caused one of the world's greatest humanitarian crises and wrecked the economy in a country which relies on oil production for the vast bulk of its revenues.

The United Nations and the African Union earlier this month appealed to the country's warring parties to make concrete steps to implement the latest accord.

South Sudan gained independence from its northern neighbour Sudan in 2011 after a 22-year civil war pitting rebel groups against Khartoum.

Several ceasefires and peace agreements have so far failed to end the fighting in South Sudan that has killed an estimated 380,000 people, uprooted a third of the population, forced nearly two-and-a-half million into exile as refugees and triggered bouts of deadly famine.

Sudan earlier this month appointed a peace envoy to South Sudan following the signing of the September accord in Addis.
