MAIDUGURI, Nigeria - Two female suicide bombers killed at least 21 people on Tuesday in a busy market area of Nigeria's northeastern city of Maiduguri, center of a militant Islamist insurgency, emergency services said.
Four witnesses told Reuters near the scene that a woman had entered the roadside trading area behind the city's main market before blowing herself up.
"While the people were trying to help the injured, the second bomb blasted," witness Sani Adamu told Reuters. "I saw lots of bodies".
An official at the National Emergency Management Agency (NEMA) said 21 bodies had so far been removed from the scene of the twin blasts, while a medical worker said a local hospital where he was based had received some 13 bodies.
Nigerian authorities did not immediately respond to requests for comment. There was no claim of responsibility, but suspicion is likely to fall on violent Islamist group Boko Haram, whose five-year campaign for an Islamic state has killed thousands.
