DAKAR, Senegal — A blast in the northeastern Nigerian city of Yola on Tuesday night tore through a marketplace, killing 32 people and wounding 80 others, according to the local authorities and witnesses.

The blast occurred at 8 p.m. at a market filled with shoppers stocking up on fruits and vegetables for dinner, turning the area into a horrific scene of blood, bodies and mayhem.

No one claimed responsibility, but officials suspected the militant Islamic group Boko Haram, which has unleashed years of violence in the region. A police spokesman, Othman Abubakar, said officials were investigating.

Nigeria has increased its fight against Boko Haram as part of a pledge from the new president, Muhammadu Buhari, to finish it off by the end of the year.
