A rebel-appointed official in South Sudan's war-ravaged Unity state says government troops on Sunday attacked a village on the first day of a cease-fire that both sides have pledged to implement.

John Riek, who coordinates relief activities in an opposition-held part of southern Unity state, accused government troops of attacking Jabuar village following what he said were attacks on two other villages in the area Saturday night. He said government troops were burning houses and looting livestock on Sunday.

The Associated Press could not independently verify his claims.

Military spokesperson Col. Philip Aguer said he was unable to verify reports of clashes. Rebel spokesman James Gatdet Dak said he has not received reports of new clashes.
