The UN children's agency, Unicef, says some 535,000 children in Burkina Faso are suffering from acute malnutrition.

Unicef says many of those affected have been displaced by jihadist and ethnic conflicts.

The coronavirus pandemic had made the situation worse, it adds, restricting access to food and healthcare.

More than 150,000 of the affected children have been classed as severely malnourished, which means they are nine times more likely to die than well-nourished children.

There has been an upsurge of Islamist violence in Burkina Faso in recent months.
