The death toll from a suicide bombing at a market in the northeastern Nigerian town of Yola rose to 45 on Friday, authorities said.
There was no claim of responsibility for the attack but it bore the hallmarks of Islamist militant group Boko Haram.
The suicide bomber struck at around 1900 GMT (1500 ET) on Thursday in the Jimeta district of Yola, the capital of Adamawa state.
“Ten more people died this morning,” police spokesman Othman Abubakar told Reuters, adding to the 35 bodies that a senior policeman, who wanted to remain anonymous, earlier said he had seen at the bomb scene. Around 40 people were wounded, said Abubakar.
Boko Haram has waged a six-year insurgency to try to set up a “caliphate” in the northeast of Africa’s biggest oil exporting country, but government counter-offensives this year have retaken much of the territory held by the jihadists.
In his inaugural speech, Buhari – a Muslim – promised to eradicate the “mindless, godless” group and rescue hundreds of women and children held captive by the jihadists, including 200 girls taken from the town of Chibok a year ago.
