A minibus has hit a landmine in Burkina Faso in West Africa, killing at least 10 people, officials say.

Five others were wounded in the blast, which occurred in the east, near the border with Niger, on Christmas Day.

The governor of the Fada N'Gourma region said the death toll could rise as some passengers were still missing.

Burkina Faso and its neighbours have faced jihadist insurgencies since 2013. The crisis has killed thousands of people and displaced more than 2m.

The military seized power in Burkina Faso last January, promising an end to attacks but the violence still rages.

French troops have been trying to help the region's armies tackle militants since 2013.

In August French troops withdrew from Mali after a diplomatic fall-out with the country's military rulers, however, they remain in other Sahel countries.
