The United Nations mission in the Democratic Republic of Congo says another peacekeeper has died after being wounded in the deadliest single attack on a UN peacekeeping mission in almost 25 years.

The mission known as Monusco says on Twitter that the incidence brings the toll to 15 Tanzanian peacekeepers killed in the December 7 rebel attack on a UN base in eastern DRC.

The attack has been blamed on the Allied Democratic Forces, one of dozens of armed groups that roam the mineral-rich region.
