Over 70 additional people are being treated for wounds. The attacks occurred on Tuesday, but because of technical problems with area telephone lines, the news became public on Wednesday.
Striking a refugee camp called Dikwa, 50 miles outside the capital of Borno state, the bombings were reportedly carried out by two female bombers. A third female bomber was arrested and provided officials with information about future planned bombings. The camp has increased its security measures as a result.
Witnesses say the bombers infiltrated the camp and set off the blasts during breakfast on Tuesday morning.
"Between 6:00 am and 7:00 am when people were trying to line up for breakfast an explosive went off. In the ensuing confusion another blast went off again," witness Mustapha Ali told Nigeria's Channels Television.
"We do not have control over our movement — only the government decides where we stay, but we wish they would relocate us to Maiduguri because we are in a war zone. Even though we are surrounded by soldiers."
The camp hosts approximately 50,000 people and was set up for individuals displaced by the terrorist group Boko Haram. Officials are blaming Boko Haram for the incident.
During its six-year insurgency, Boko Haram has killed approximately 20,000 people displaced as many as 2.5 million in Nigeria.
