At least 30 people have been killed in a suicide bomb attack in the north-eastern Nigerian town of Madagali in Adamawa state, the army says.
Two female suicide bombers detonated their explosives in a busy market, an army spokesman told AFP news agency.
No group has said it was behind the attack.
But Islamist militant group Boko Haram has been waging a seven-year insurgency against the government and often uses suicide attacks.
Dozens of others were wounded in the bombing, army spokesman Major Badare Akintoye said.
The two bombers, who were “disguised as customers, detonated their suicide belts at the section of the market selling grain and second-hand clothing,” local government official Yusuf Muhammad told AFP.
A rescue team has arrived at the scene, Nigeria’s National Emergency Management Agency (Nema) said.
Boko Haram occupied Madagali for several months until it was driven out last year.
A regional force has retaken most territory under the group’s control in the past 22 months.
But as it advances into areas previously controlled by the Islamists, the army has found tens of thousands of civilians on the brink of starvation.
The number of people facing starvation in the north-east of Nigeria is as high as 120,000, of which 75,000 are children, the UN warned earlier this month.
More than two million people have been forced from their homes as a result of the Islamist insurgency. BBC News
