Abuja - Local Nigerian officials say a teenage girl packed with explosives by a Nigerian rebel group ripped off her vest to avoid taking part in an attack on a refugee camp.
Two others with her, however, walked into the middle of hundreds of people lining up for food before they blew themselves up in an attack on Tuesday that killed 58 and wounded 78 in Dikwa, northeast Nigeria.
Self-defence fighter Modu Awami said on Thursday that the third bomber, looking about 14, has confessed.
Awami, who helped question the girl, says she was scared because she knew she would kill people.
A rescue official says the girl has given officials information about other planned bombings.
