Five suicide bomb explosions tore through the northeastern Nigerian city of Maiduguri, an official told the Associated Press. At least 54 people are dead and 143 wounded.

Agence France-Presse reported earlier that three bombings had left at least 33 people dead:

The first attack by a female suicide bomber at roughly 11:20 am (1020 GMT) killed 18 people at the Baga fish market, and another 15 were killed about an hour later at the Monday Market, said fisherman's union boss Abubakar Gamandi, in an account supported by other witnesses and a health worker.

While the militant Islamist group hasn't yet claimed responsibility for these most recent bombings, Boko Haram have laid siege to Maiduguri, a city of two million people, for the past several months, using a young girl as a suicide bomber in January.
