Ugandan troops have killed a top bodyguard of Lord's Resistance Army leader Joseph Kony.

A Ugandan army official said Monday that troops killed the rebel known as Binani during an operation Friday in the eastern part of the Central African Republic, near South Sudan.

Ugandan troops have been working as part of an African Union force, with the help of U.S. military advisers, to hunt Kony and other LRA members.

The LRA was once based on northern Uganda and is accused of killing, kidnapping and mutilating tens of thousands of people across central Africa over the past 25 years.

Kony is wanted by the International Criminal Court for war crimes and crimes against humanity.
