Two explosions ripped through a crowded mobile phone market in the northeast Nigerian city of Potiskum on Sunday, residents said, a day after a car exploded outside a police station, killing at least two.
The blasts rocked the Kasuwar Jagwal market within seconds of each other at about 3:10 pm (1410 GMT), when business was at its peak, but there were no immediate indications of the number of casualties.
"The first explosion happened inside the market and the second went off just outside the entrance as people rushed out to flee," said witness Ibrahim Dambam.
