Dozens of people have been killed by a suicide bomb attack during morning prayers in a mosque in north-east Nigeria.
Boko Haram, the militant group that has killed tens of thousands of people and displaced millions in the region, is thought to be behind the attack in Mubi, a town in Adamawa state, but has not yet claimed it.
The group has used children as young as five to carry out hundreds of attacks on busy marketplaces, checkpoints and mosques in the past few years, but the death toll from the Medina mosque is among the highest.
Pictures posted on social media in the aftermath of the attack showed bloodstains on the floor of the mosque, which had a gaping hole in its wall.
A police spokesman, Othman Abubakar, told reporters that the death toll was at least 50, though a reporter on the ground said 27 people had died, all of them men and boys.
