The Ugandan army said on Sunday that it had killed 10 fighters of the rebel Lord's Resistance Army (LRA) in an ambush and battles in northern Gulu district over the weekend.
"Ten LRA fighters have been put out of action between yesterday (Saturday) and today," army spokesman Lieutenant Kiconco Tabaro told AFP by phone.
Six insurgents were killed on Saturday in an ambush along River Odek and a battle in Latwong forest in Gulu district, the epicentre of fighting between the military and the rebels, he said.
"We killed four this (Sunday) morning during a battle at Karajuti area also in Gulu," Tabaro said.
Soldiers rescued 51 children from various rebel hideouts in Gulu district. The children were among scores of others who were abducted on Thursday from the neighbouring Apac district, the army claimed.
Around a dozen children have since escaped.
Several attempts to sign a truce and launch formal peace talks have failed amid growing mistrust between the warring sides.
The LRA, which operates from bases in northern Uganda and southern Sudan, has been fighting President Yoweri Museveni's secular government since 1988, ostensibly to replace it with one based on the biblical Ten Commandments.
It is notorious for its brutality against the people of northern Uganda, where more than 1.6 million people have been displaced from their homes and are living in squalid camps.
The rebel group tends to swell its ranks by raiding camps for displaced people in northern Uganda and kidnapping children living there, forcing the boys into combat, the girls into sexual slavery.
