United Nations (UN) has accused South Sudanese rebels of violating a ceasefire by launching an offensive to recapture its former headquarters.
The attack on Nasir town was the “most serious resumption of hostilities” since May, the UN said.
The rebels said they had seized the town in an act of “self-defence”. The government denied the town had fallen.
Fighting between government and rebel forces broke out in December, leaving more than a million homeless.
President Salva Kiir and rebel leader Riek Machar met in May and recommitted themselves to a ceasefire negotiated in January by regional leaders.
Rebel spokesman Lul Kuang said they launched an offensive because of several attempts by government forces to arrest their commander.
“The fall of Nasir now paves the way for military resources to be refocused on Poloich Oil Fields, Maban and Malakal,” Mr Kuang said in a statement.
