Bamako (Mali): Two UN peacekeepers were shot dead and another injured by their Chadian colleague, the UN mission in Mali said on Sunday.
Authorities arrested the peacekeeper but the reason behind the shooting was still unknown, spokeswoman for the UN mission in Mali Radhia Achouri was quoted as saying by Xinhua.
This was not the first time that UN peacekeepers were killed by colleagues.
Last month, a Chadian soldier killed his own commander and an army doctor over living conditions.
