Three bomb blasts targeting separate areas in northeast Nigeria's largest city of Maiduguri on Saturday, killed at least 54 people, wounded 143.
Many children were among the dead in the explosions that hit two crowded markets and a busy bus station.
The first attack by a female suicide bomber took place at 11:20 am killing 18 people at the Baga fish market. About an hour later at the Monday Market 15 more people were killed, said fisherman's union boss Abubakar Gamandi, in an account supported by other witnesses and a health worker.
Borno state Justice Commissioner Kaka Shehu confirmed those two blasts and said a third bombing hit the busy Borno Express bus station just after 1:00 pm.
