YAOUNDÉ - Nineteen people were killed in Thursday night's attack on a Cameroonian village by Nigeria-based Boko Haram militants, a security source said in an updated toll, adding that most of the victims were beheaded.
"The final toll from this attack is 19 dead, with a majority of the victims decapitated," a security source said Saturday on condition of anonymity.
The attack comes after a regional military offensive - which includes Cameroon - has claimed a string of successes in their fightback against the Islamist militants in Nigeria in recent weeks.
Bia, which borders Lake Chad, has been identified previously by security forces as a recruiting ground for Boko Haram militants.
The source speaking to AFP on Saturday said security forces were slow to react to the raid on Bia, located in an area with several military bases.
"We noted a late response by our forces,", the source said.
"Many huts were burned down," the source added.
Also during the night from Thursday to Friday, Boko Haram Islamists attacked a Cameroon army position in Amchide, on the border with Nigeria.
"They burned houses in Amchide, but without losses on our side. The attack was repulsed. We don't know yet about casualties on the enemy side," a security source told AFP on Friday.
The insurgency by Boko Haram - which is seeking to create a hardline Islamic state - has killed some 13,000 people in northeast Nigeria and sent 1.5 million fleeing their homes since 2009.
The group had in recent months widened its attacks into neighbouring nations, prompting Chad, Cameroon and Niger to launch a joint offensive with the Nigerian army, resulting in a series of rebel-held towns and villages being recaptured in Nigeria's northeast.
Nigerian President Goodluck Jonathan's perceived inability to end the six-year insurgency was a factor in his election defeat last month.
Nigerian President-elect Muhammadu Buhari has vowed to rid the country of the "terror" of Boko Haram.
