The insurgents Boko Haram terrorist group has killed eleven people and wounded two on the Sallah Day at the Internally Displaced Persons, IDPs, camp in Banki town, bordering Cameroon.
The group was said to have, in the early hours, infiltrated the camp in Banki which has about 45,000 persons, attacking, killing and injuring their victims quietly with knives.
They adopted this silent tactics to avoid being challenged by soldiers at a nearby military camp.
They were also said to have carted away food belonging to the displaced persons.
The terrorists were believed to have used knives instead of firearms or explosives in order not to alert soldiers who were close by, thereby inviting counter-attack.
However, soldiers were reportedly alerted once the attack was discovered and moved in to dislodge the insurgents.
Banki town has come under repeated attacks by Boko Haram.
In April last year, at least seven people were killed at the camp in a suicide bombing attack carried out by two women.
In January of this year also, a 10-year-old girl died in a botched suicide bombing attack just outside the camp, according to a PM news report.
