Witnesses reportedly said a girl who killed herself and at least five others in an attack on a market in northeastern Nigeria could not have been more than eight years old.
The region is increasingly anxious that Boko Haram is infiltrating villages along the border to facilitate attacks and expand the dubious “caliphate” it declared in northern Nigeria.
Militants reportedly attacked residents in their homes and at a mosque in the Nigerian border-town of Fotokol Wednesday.
An operation led by Cameroonian armed forces won Nitsch Eberhard Robert's release while a purported Boko Haram video answered for an attack in Borno State that killed anywhere between 150 to 2,000 people.
The estimated number of casualties in the town of Baga vary wildly, but one local official claimed 2,000 people had been killed in the Boko Haram attack.
With one month to go until Nigeria's elections, the Islamist insurgents, battling to carve out a caliphate in the country's north, are gaining ground.
