Militants claiming loyalty to Islamic State said they were behind suicide bombings carried out in the Federal Capital Territory (FCT), Friday, which killed at least 20 people, a statement on their Twitter handle said, Sunday.
While President Muhammadu Buhari had blamed Boko Haram, which has waged a six-year campaign to carve out an Islamist state in northern Nigeria, for the Kuje and Nyanya attacks, the militants claiming loyalty to Islamic State said they had conducted the suicide bombings, according to the statement.
The authenticity of the statement, which did not mention Boko Haram and was issued under the name Islamic State West Africa, could not be verified.
It named three suicide bombers who it said were behind the attacks, the statement said.
In May, the leader of the Islamic State militant group that controls parts of Syria and Iraq accepted a pledge of allegiance from Boko Haram, according to his spokesman, even as the extent of cooperation between the two groups is not known.
Islamic State, an ultra-hardline offshoot of al Qaeda, has declared a caliphate, a state governed in accordance with Islamic law, in captured territory in Iraq and Syria.
The militants have gained global notoriety for killing or kidnapping members of ethnic and religious minorities and posting videos of its members killing Arab and Western hostages.
