Kigali - A military official says an army major has been shot and killed by a colleague in a remote area of Burundi.
Army spokesperson Colonel Gaspard Baratuza says in a statement that the alleged killer of Major Dieudonne Karashira has been arrested and is under interrogation.
He has no information on the possible motive behind the Wednesday night attack.
This is the latest incident in nearly two years of political violence sparked by President Pierre Nkurunziza's decision to extend his rule beyond two terms.
Karashira was attached to Cankuzo military camp about 200km from the capital, Bujumbura.
Baratuza says Karashira was in charge of intelligence at the military camp and was killed while on patrol.
Burundi accuses Rwanda of backing rebels opposed to Nkurunziza, charges that Rwanda denies.
