UN troops have been battling to curb attacks by insurgents in Mali

A fourth United Nations peacekeeper has died of his injuries following an attack by suspected jihadists in Mali.

Five others were wounded when their convoy struck an explosive device and came under fire near the town of Bambara-Maoudé in the Timbuktu region on Wednesday.

Islamist groups linked to al-Qaeda and Islamic State operate in the area and have made much of the country ungovernable.

The peacekeepers, who were part of the UN mission in Mali, came from Ivory Coast.
