A 13-year-old girl has said she was made to wear a bomb belt and taken to a market in Nigeria by Boko Haram extremists but refused to detonate the device.
Zahara'u Adam said her father gave her to the Islamist group, but she told her captors she did not want to be a suicide bomber.
She allowed them to strap the bomb on her because they threatened to bury her alive.
She was taken to a market in Kano, Nigeria's second largest city in the north, with two other girls, who detonated the bombs.
Four people were killed in the explosion on 10 December.
Zahara'u said she was too scared to detonate the bomb when she saw the aftermath of what her counterparts had done.
Injured by the blasts, the girl found her way to a hospital where police arrested her while she was receiving treatment.
She was presented to journalists by police and instructed to recount how the militants allegedly forced her to take part in the attack - a move police hope will boost public awareness of the group's tactics.
"My father took us to the bush which was surrounded by gunmen, I was asked if I want to go to heaven, when I answered they said I have to go for a suicide mission and if I attempt to run, they will kill me," she recounted at a press conference.
"So from there we were sent to Kano. When we came to Kano market, one of us said we should go separately, but I refused.
"After my friend detonated her own I was wounded."
There was no way to independently verify her story and she had no lawyer present.
Boko Haram has been fighting for five years to establish an Islamist state in Nigeria's northeast.
The group has increasingly used female suicide bombers.
