A suicide bomber killed about 16 people at a crowded market early Friday in a blast that thundered across the northeastern Nigerian city of Maiduguri, witnesses said.
The region has been pummeled by suicide bombings that have killed hundreds carried out by the Boko Haram Islamic extremists since Nigeria elected a new president who promised to root out the extremists. A police bomb expert said the bomber was a man, not a woman as had been originally described by witnesses.
