A female suicide bomber has blown herself up, killing at least a dozen people in a market in the Nigerian town of Azare.
No one claimed immediate responsibility for the blast, but Boko Haram, which has waged a bloody five-year campaign to establish an Islamic state in northern Nigeria, is suspected of having carried out a wave of attacks this week.
The group has also seized two towns and occupied a third in the country's northeast region since it rejected a ceasefire announced last month by the government.
An official at the town's hospital said six bodies were brought in and four other people had later died there of their injuries.
The state's government and police officials were not immediately available to comment.
At least seven people were killed on 7 November by a blast outside a branch of the First Bank of Nigeria in Azare. Police said at the time they believed a female suicide bomber was responsible for the explosion.
Azare is about 100km west of Potiskum, where a suicide bomber blew himself at a school last Monday, killing 48 people.
Nigeria's President Goodluck Jonathan, who is seeking a second term in a February 2015 election, has vowed to defeat the Islamist militants, who are seen as the biggest security threat to Africa's largest economy and top oil producing nation.
Boko Haram, whose name means ‘Western education is sinful’, has attacked schools, abducted hundreds of students and killed thousands in its fight for an Islamist state.
