The Ugandan military says it attacked a hideout of rebel leader Joseph Kony in southern Sudan this week, killing four of his bodyguards.
A military spokesman, Lieutenant Chris Magezi, says soldiers clashed with rebels commanded by Kony southwest of Juba on Tuesday.
The spokesman says one Ugandan soldier was wounded in the battle. He says Kony and his fighters are now fleeing a Ugandan offensive, heading toward the Democratic Republic of Congo.
Sudan allows Ugandan forces to pursue Kony and other leaders of the rebel Lord's Resistance Army on its territory. The International Criminal Court has issued arrest warrants for Kony and four other LRA leaders.
The group is notorious for its brutality and use of child soldiers in northern Uganda. The group's 20-year uprising has displaced more than 1.5 million people.
