Rescue workers transport a victim of a suicide bomb attack at a refugee for treatment at a hospital, in Maiduguri, Nigeria, Wednesday, Feb. 10, 2016.

Health and rescue officials say two female suicide bombers blew themselves up in a northeast Nigerian refugee camp, killing at least 56 people.

They say a further 78 people are being treated for wounds in the twin explosions Tuesday morning in a camp of some 50,000 people driven from their homes by the Boko Haram Islamic uprising.

Officials blamed the extremists for the bombings at Dikwa, 85 kilometers northeast of Maiduguri, the biggest city in the region and birthplace of Boko Haram.

The 6-year-old insurgency has killed 20,000 people, made 2.5 million homeless and spread across Nigeria’s borders.

The governor of neighboring Cameroon’s Far North province said two suicide bombers believed to have come from Nigeria on Wednesday killed 10 people and injured 40 in a border village.
