A UN peacekeeper was killed by a mine on Sunday in restive northern Mali as he was participating in a patrol, the head of the UN's MINUSMA Mali force El Ghassim Wane tweeted.

The peacekeeper was part of the Guinean contingent in MINUSMA, a MINUSMA official told AFP on condition of anonymity. "He was first wounded and died of his injuries at our hospital in Kidal," he added.
