The Cameroonian government says that terrorism threatens large numbers of schoolchildren. Two bomb attacks killed nine people last month in the town of Kolofata, near the border with Nigeria. At the same time, millions of children returned to school after a three-month holiday. Cameroon has been working to make its school campuses safer.

One of the most dangerous areas is along the border with Nigeria.

Many families want to leave the dangerous border areas. Sixteen-year-old Ahmidou Moussa was not able to return to school on time because of the threat of suicide bombings. His school is in the town of Mora, on the border with Nigeria.

He says he was not really worried during the holiday because his parents took him far away from the dangerous border zone to a safer area.

Valentine Tameh is president of the Teachers Association of Cameroon. He says many teachers are refusing to teach in areas along the border with Nigeria. He says he has told teachers to continue to work even in the border area.
