A local official in northern Cameroon says at least nine people were killed and dozens injured when suspected Boko Haram militants carried out a suicide attack on a town bordering Nigeria.

Midjiyawa Bakary, governor of Cameroon's Far North region, said the attack took place in the town of Fotokol. He couldn't provide more details but said a crisis meeting with military officials had been convened.

Fotokol has been targeted by suicide bombers multiple times this year, most recently on Nov. 9 when a female teenage suicide bomber hit a mosque during afternoon prayers, killing at least four and wounding dozens.

Cameroon is contributing troops to a regional force to fight Boko Haram, whose six-year insurgency has left an estimated 20,000 people dead, according to Amnesty International.
