The UN must conduct a “thorough investigation” into its peacekeepers’ actions in Central African Republic during a militia attack in which “up to 100 civilians were shot and burnt alive”, Amnesty International said Friday.

In a new report, the London-based watchdog said troops in the UN’s MINUSCA mission had retreated to their base rather than engage with a militia group which attacked civilians at a displacement camp at the Catholic mission in the central town of Alindao in mid-November.

According to an internal UN report, at least 60 people were killed when violence flared between the Union for Peace in CAR (UPC) Muslim militia and anti-Balaka militiamen.
