"Today is the market day here and at 9:50 (0850 GMT) this morning, a female suicide bomber blew herself up at the... Entrance of the market where commuters were arriving," market trader Garba Abdullahi told AFP.
"We evacuated 15 dead bodies to the hospital, including the suicide bomber who was identified as a mentally unstable woman that had been known for years in the area," he said, adding that the bomber was around 40 years old.
"We have received 15 dead bodies and 47 people with injuries from the market blast site. Eight of the dead are women. One of them, from all the indications, was the suicide bomber," added the nurse from the Sani Abacha Specialist Hospital, who requested anonymity.
"Most of the injuries are serious," she added.
Damaturu was the scene of a triple suicide bombing on July 18 when three girls blew themselves up killing at least 13 people as residents prepared for the Eid festival marking the end of Ramadan.
A new wave of violence has left 800 people dead since Nigeria's President Muhammadu Buhari came to power in May.
Buhari has made it a priority to tackle the insurgents, who are linked to the Islamic State organisation that has seized swathes of Iraq and Syria.
