JUBA, South Sudan — South Sudan's minister of information says that most of the 25,000-strong militia that had been marching toward a potentially vicious military confrontation has disbanded and returned home.

Michael Makuei Lueth told The Associated Press Sunday that Nuer community leaders in Jonglei state persuaded the "White Army" fighters to go home.

Lueth said only a "very few" refused to disband. He said an exact number was not known.

South Sudan has had two weeks of violence. The government accuses former Vice President Riek Machar, an ethnic Nuer, of a coup attempt against President Salva Kiir, a Dinka.

Lueth on Saturday told a news conference that more than 25,000 Lou Nuer youth were marching toward Bor.

The United Nations Sunday said it was "extremely concerned" and urged the fighters to return home.
