Bombing attacks killed nearly 30 people in the Nigerian city of Maiduguri over the weekend, according to reports.
At least four people were critically injured -- with one losing an arm -- when an improvised explosive device detonated in the Gamboru Market in Maiduguri on Sunday, according to Nigerian media.
The blast occurred less than 24 hours after a suicide bomber detonated in a mosque at the Monday Market in the same city, killing 26 people and injuring 28.
Militant Islamic group Boko Haram is suspected of the attacks, which follow Friday's inauguration of President Mohammadu Buhari. A former military officer, Buhari won Nigeria's late-March election over former President Goodluck Jonathan and last week said he would move the Nigerian military's command and control center from Abuja to Maiduguri "until Boko Haram is completely subdued."
Buhari condemned the weekend attacks and expressed condolences to the families of the victims.
Reports indicate that barely 12 hours prior to Saturday's mosque explosion, the Nigerian military repelled Boko Haram gunmen from portions of Maiduguri, which is the capital of Borno state in the country's northeast, in a firefight that killed 16 people. The insurgents also reportedly attacked the village of Malari, which is in the same province, with rocket-propelled grenades, car bombs and anti-aircraft weapons, killing 15.
Boko Haram has since 2009 sought an Islamic government in Nigeria, targeting Maiduguri several times, including in a failed assault on the city earlier this year and through multiple suicide bombings, many utilizing young women as perpetrators . Experts have speculated the group might be using abducted children to conduct some of the attacks.
