Khartoum, Sudan (CNN) -- South Sudan's government has gained control of a remote town that had been under attack by fighters from a rival tribe, the nation's information minister said Monday. Some of the thousands who fled into the bush have begun to return to Pibor, said Barnaba Benjamin, South Sudan's minister of information and broadcasting. Earlier Monday, a military official said that roughly 4,000 army and police reinforcements were on the way to Pibor after weekend attacks. The United Nations also said it sent a battalion of peacekeepers to Pibor last week amid reports that members of the Lou Nuer tribe were marching toward the town, home to the Murle tribe, after attacking the village of Lukangol.
