The decision comes a month after fighting broke out between army rival factions that has put peace deal in danger.
Ayaa Joyce and Beatrice Masudio might come from different parts of South Sudan but they are united in sorrow.
Having lost their husbands in the country’s latest round of violence, the two women gathered their children and few belongings and made the dangerous journey to reach refugee camps in neighbouring Uganda.
“When we reached the checkpoint, three people had been killed by some armed men,” Joyce told Al Jazeera’s Catherine Soi in northern Uganda’s Elegu town.
“Soldiers were gathering. They stopped us and searched us. When they realised we were from the Madi tribe, they let us go.”
Approximately 70,000 people have now crossed the South Sudanese border with Uganda since fighting erupted in the capital, Juba, between forces loyal to South Sudan’s President Salva Kiir and his former Vice President Riek Machar in early July.
Like Joyce and Masudio, the majority of the South Sudanese refugees in Uganda are women and children.
Alice Sunday, a 16-year-old from Juba, said many people had died in the recent fighting, and she and others had to sleep outside without shelter or food. Her school was closed down.
“What brought me from Juba is the war taking place in Juba …. Many people die. That is why we are here to save our life,” Alice also told our correspondent in Uganda’s Yumbe.
“We came here so we can get school and get food.”
This is the second time the teenager has been displaced by fighting. The first time was in 2013 when civil war erupted and she fled to Yei in South Sudan’s Central Equatoria region.
“We just want our future to be good,” Alice said of her second escape from the conflicts that have torn her country apart.
Almost 300 people, including at least 73 civilians, were killed in the recent fighting in Juba.
More than 1.6 million people in total have been displaced in the country due to conflict in recent years.
South Sudan was founded with optimistic celebrations in the capital on July 9, 2011, after it gained independence from Sudan in a referendum that passed with nearly 100 percent of the vote.
The country descended into conflict in December 2013 after Kiir accused Machar of plotting a coup.
Civil war broke out when soldiers from Kiir’s Dinka ethnic group disarmed and targeted troops of Machar’s Nuer ethnic group.
Chol Yoro worked in a bank in Sudan’s capital, Khartoum, before returning to South Sudan when the country achieved independence.
He says he moved back to help develop his country.
“But, unfortunately, I got the opposite, which is the war,” said Yoro, who is now a refugee in Uganda with his family.
“I’m very unfortunate.”
Those fleeing the latest violence are screened as they cross the Ugandan border.
They are then put on buses and driven for hours over bumpy roads to reach settlement areas set aside by the Ugandan government.
“We’ve had wide-scale reports of sexual assault being committed against women and young girls,” he said.
In some areas, armed groups are reportedly visiting schools in order to recruit boys and young men into their ranks.
Al Jazeera’s Soi, reporting from a refugee settlement in Yumbe, described the situation as “very dire”.
“Refugees who have come here are traumatised and tired. It’s a new settlement. Things are still being set up.
“Refugees are being given basic supplies like food and basins, cooking pots and things like that and they’re also construction material to build new shelters.
“This land was provided by the government. It’s a heavy thicket. So it’s going to take a while for them to clear the thicket and put up the structures.”
