Two female suicide bombers have blown themselves up in a Nigerian refugee camp, killing at least 56 people, officials said.
A further 78 people were being treated for wounds in the twin explosions on Tuesday 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, 55 miles north-east of Maiduguri, the biggest city in the region and birthplace of Boko Haram.
The six-year-old insurgency has killed 20,000 people, made 2.5 million homeless and spread across Nigeria’s borders.
The governor of neighbouring Cameroon’s Far North province said another two suicide bombers believed to have come from Nigeria on Wednesday killed 10 people and injured 40 in a border village.
