A bomb has exploded at a market in Potiskum, Yobe State, with many people feared dead, the News Agency of Nigeria has reported.
The blast occurred on Sunday at the GSM market in the city.
Some survivors suspected that a female suicide bomber detonated the explosive, killing herself and others at the busy market.
Toyin Gbadegesin, the Police Public Relations Officer in the state, confirmed the attack to the News Agency of Nigeria (NAN).
“Yes, there was a bomb attack at the Potiskum GSM market and our men have moved to the scene for rescue operation and to get details of the incident,” he said. “As at this moment, we do not have the details of deaths and injuries. Our men are still collating the details.”
Other survivors said the bomb exploded after an argument between the suspected bomber and local security men at the market.
The blast was the second on the market this year, with the first killing seven people and injuring many others.
No group has claimed responsibility for the attack yet, although jihadist group, Boko Haram, is suspected.
Yobe State has suffered several attacks from the terror group, with multiple bomb and gun attacks targeting the military and civilians.
Yobe lies next to Borno State, which is at the centre of a six-year long Boko Haram insurgency.
