Two female suicide bombers blew themselves up killing at least ten people on Tuesday in a crowded market area of Nigeria's northeastern city of Maiduguri,centre of a militant Islamist insurgency, witnesses 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".
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 5-year-old campaign for an Islamic state has killed thousands.
