South Sudanese rebels said that government forces had attacked several of their positions on Friday, a day after a cease-fire was signed that was supposed to bring an end to a monthlong conflict that shook the new country and displaced hundreds of thousands of its citizens.
Analysts cautioned that enforcing a cease-fire would be far more daunting than agreeing to one.
A news release from the opposition that was sent to reporters on Friday charged that the army of President Salva Kiir, along with Ugandan forces, went on the offensive in Jonglei and Unity States.
In Jonglei, the release said, “the attackers were repulsed and suffered heavy casualties.”
