Only doctor left in Cameroon town treating wounded Nigerians 'killed in Boko Haram attack'

About 13 bodies have been discovered in a primary school building in the Cameroonian town of Fotokol which borders Nigeria.

Residents say they were killed by rockets fired by suspected Boko Haram militants from Gamborou town on the Nigerian side of the border.

The dead are said to include the only medical doctor who remained in the town to look after refugees who fled from the conflict in north-east Nigeria.

Cameroon along with Chad and Niger is helping Nigeria in the fight against the Islamist insurgents.
