At least 50 people have been killed in a suicide bombing in the north-eastern Nigerian town of Mubi, police say.
A bomber struck inside a mosque packed with worshippers during morning prayers in Adamawa State.
Witness Abubakar Sule told AFP news agency that it appears the bomber was part of the congregation.
No-one has said they were behind the bombing but the Islamist militants Boko Haram typically target crowded places in northern Nigeria.
Some 20,000 people have been killed in Boko Haram’s eight-year insurgency.
The BBC’s Ishaq Khalid reports Boko Haram militants have recently stepped up suicide bombings in Nigeria’s north-east after the military recaptured territories previously controlled by the group.
