UN peacekeeper shoots dead 2 colleagues

The UN peacekeeping mission in Mali says a peacekeeper has shot dead two colleagues in what has been called a “settling of scores.”
A statement from the mission on Friday says the suspect was immediately detained after the shooting at the UN base in Kidal in northern Mali. An investigation is under way.
A peacekeeping official says the Chadian peacekeeper shot a commander and doctor.
It was not clear what caused the shooting.
Mission spokesperson Olivier Salgado says operations at the base have returned to normal.
The UN mission in Mali has been one of the world body’s deadliest peacekeeping missions.
