"We just had an explosion, nobody can confirm the cause. No loss of life or injuries were recorded. The area is being evacuated," a police spokesman in the city, Magaji Majia, told AFP.
Army spokesman Lieutenant-Colonel Iweha Ikedichi gave a similar account of the incident.
A witness however claimed two people were injured.
Soldiers and police have cordoned off the area, an AFP correspondent said.
"There was an explosion, there was no injury or death," an on-duty soldier told AFP.
Locals say the area, known as New Road, holds a bus terminal for people travelling to the country`s eastern region, the home of the mainly Igbo ethnic group of Nigeria.
Last week 185 people died in Kano in multiple and coordinated bomb and gun attacks claimed by the Islamist group Boko Haram.
A Nigerian police source told AFP on Thursday that roughly 200 people had been arrested following that attack. (*)
