Four people were killed when suicide bombers attacked a school in Cameroon's Far North Region on Thursday morning, a military source told dpa.
The two suspected Boko Haram attackers were targeting a school in the locality of Kerawa, according to Joseph Nouma, the commander of Cameroon's elite force fighting the Islamist group in the region.
"They detonated the explosives near the school, killing two women and wounding 38 others. Twelve of the wounded are in a very critical state," he said.
The two attackers were also killed in the bombing.
On Monday three suicide bombers had blown themselves up in the village of Bodo in northern Cameroon, killing at least 25 people and themselves.
A security official who did not want to be identified said the terrorists, who targeted the market, carried the explosives in vegetable bags.
Cameroon has become a major target for Nigeria-based Boko Haram. The group has killed nearly 1,200 people in Cameroon since 2013, according to the government.
