Two suicide bombers hit a market in the north Cameroon village of Meme, killing at least 22 people, and two others targeted a school in a nearby town on Friday, a Cameroon governor said.
The attackers at the market disguised themselves as food vendors, said Far North Gov. Midjiyawa Bakari. The 105 wounded are being treated at the hospital in the nearby town of Tokombere, some in critical condition, he said, AP reported.
The other two attackers were targeting a school in Tokombere, but detonated their explosives in the bush about 1 kilometer from the school after they were identified, said teacher Mamoudou Gonit.
He said the explosions caused panic among teachers and students who ran in different directions, but no one besides the bombers was hurt. Boko Haram militant group was suspected of the attack.
In its six-year insurgency, Boko Haram has killed more than 20,000 people and displaced 2.8 million in the region, according to the United Nations and Amnesty International. Boko Haram violence in Cameroon has caused about 1,000 deaths, according to the Cameroon government and military sources.
Boko Haram is thought to have killed about 15,000 people and driven more than two million from their homes during its six-year insurgency in one of the world's poorest regions.
Nigeria, Chad, Niger, Cameroon and Benin have set up an 8,700-strong regional force tasked with wiping out Boko Haram.
