Two explosions rocked a market in the Nigerian city of Kano on Wednesday, causing an unknown number of casualties.
A local journalist told VOA's Hausa service that the blasts ripped through a crowded mobile phone market late in the afternoon. Security forces and rescue workers raced to the scene.
On Tuesday, a blast in the northeastern city of Yola killed more than 30 people and wounded at least 70.
No one has claimed responsibility but suspicion has fallen on militant group Boko Haram.
The Yola bombing was the first suspected Boko Haram attack in Nigeria in several weeks. Earlier this month, President Muhammadu Buhari said the Islamic extremists "are very close to defeat."
