A suicide bomber killed four people and injured 35 others in the northeast town of Potiskum, ABC news reported Sunday.
The attack in Potiskum, the largest commercial center in Nigeria's Yobe state, occurred at around 10 a.m. near a gasoline station.
There was no immediate claim of responsibility.
The suicide bombing was the third such attack this month in Potiskum, and came as Boko Haram has escalated attacks and seized more territory in Nigeria's northeast.
