Senior Cameroonian defence officials say the country has been infiltrated by Nigeria’s Islamist extremist group Boko Haram and there are fears that this central African nation, known for its stability, is drifting into chaos.

“Right now, we are being infiltrated by Boko Haram. The military has decided to strengthen the intelligence system to effectively counter this threat, which seems to be gaining local support,” Colonel Didier Badjeck, spokesperson for the Cameroon Ministry of Defence, told IPS.

Governor of Cameroon's Far North Region, Augustine Awa Fonka, told IPS that the precision with which the extremist group attacked a military post in the region on May 5, lends credence to the fact that the attack was carried out with the help of local informants.

Cameroon’s north western boarder runs along the length of Nigeria’s eastern boarder, stretching all the way to Nigeria’s predominantly Muslim north – a Boko Haram stronghold. In March, the government set up a number of military posts along Cameroon’s northwestern border with Nigeria in response to Boko Haram’s insurgency.

But on 2am, May 5, over 30 suspected Boko Haram insurgents struck the Kousseri military post in Far North Region and killed a Gendarmerie officer and a civilian being held in custody. Several people were wounded as the group freed one of their members, who was also being held at the post.

“In all of the cases (of Boko Haram attacks), especially the attack on the military post, there are quite a number of arrests that have been made. The attack couldn’t have been carried out without local informants and we believe we are going to identify these accomplices,” Awa Fonka said.

He admitted that the attack on the military was spreading fear among locals.

“The forces of law and order are there to protect the population. When they (the military) are now being attacked, it destabilises everyone,” he said.

He described the attackers as “faceless” terrorists would could only be tracked down with help of locals. He added that “every measure will be put in place to track down the attackers, or at least get their accomplices.”

Attacks in Nigeria have also resulted in refugees fleeing to safety in Cameroon. On May 6, Boko Haram – which means “Western Education is a sin” in the local Nigerian dialect, Hausa – raided a market in the Nigerian border town of Gambourou. More than 200 people, including four Cameroonians, died in the attack. Around 3,000 Nigerians, many of whom were wounded during the violence, crossed over to the Cameroonian town of Fotokol.
