More than 100 people are now said to have died in fighting in south Sudan after rebels attacked the army. Earlier reports said this week's fighting had killed 16 people. A south Sudan army spokesman said, about 39 of those killed were civilians. Twenty members of Southern Sudan's security forces were killed, along with 30 rebels, taking the new death toll to 105. During the clashes, two army trucks were blown up by land mines near the town of Fangak in Jonglei state. The clashes between fighters loyal to George Athor and south Sudan's army come as the region prepare for independence from the north following last month's referendum. According to official results, some 99 percent of people voted to secede from the north. Mr. Athor took up arms last year, alleging fraud in state elections, but signed a ceasefire last month just before the historic vote.
