A blast set off by a female suicide bomber tore through a crowded market in the northeastern Nigerian city of Damaturu on Sunday, killing at least 14 people and injuring 47, a police spokesman, quoted by Voice of America, said.

No one has claimed responsibility for the explosion, but it is the latest in a series of attacks in the last few weeks that bear the hallmarks of militant Islamist group Boko Haram.

Boko Haram controlled a swathe of land around the size of Belgium at the end of last year, but were pushed out of most of that territory by Nigerian troops in the last few months, with military help from neighboring Chad, Niger and Cameroon.
