Recent clashes between tribes in Sudan's West Darfur region have sent more than 1,800 people fleeing across the border into Chad over the past week, according to the UN refugee agency.
The majority of refugees are women, children and senior citizens who have fled villages near the border since violence erupted on April 3, said Babar Baloch, a spokesman for the UN High Commissioner for Refugees (UNHCR).
Some refugees have been forced to relocate several times after similar clashes killed more than 200 people two weeks after a joint peace mission to the region by the UN and the African Union ended in January.
"The refugees arriving in Chad talk of the destruction of their homes and possessions and targeted attacks on refugee sites," Baloch said in a statement, describing conditions in eastern Chad as "disastrous."
"Families are living in the open air or are sheltering under trees or in makeshift huts," he said.
"They have almost no protection against the elements in a region where temperatures regularly reach 40 degrees (Celsius, 104 degrees Farenheit) during the day," he said.
The vast Darfur region was previously ravaged by a civil war that erupted in 2003, leaving around 300,000 people dead and 2.5 million displaced, according to the United Nations.
A UN spokesperson told reporters on Friday that the latest bout of violence erupted between Massalit and Arab tribes in the West Darfur state capital, El Geneina, when assailants shot dead two men of the Massalit tribe.
In response, armed elements from both sides mobilized.
The Massalit are mainly farmers, while the Arab tribes are mainly herders, with the violence and divisions rooted in disputes over land, pasture and water resources, according to the UN.
The UN said it was "appalled" by the resurgence of violence, saying all tribes responsible for the bloodshed must be disarmed, with the Human Rights Office calling for independent investigations.
