Two explosions have been reported at the Wusasa and Sabon Gari areas of Zaria, Kaduna State.

Reports reaching us say an explosion occured near a catholic church in the Wusasa neighbourhood of the city.

Witnesses say security agencies have already cordoned off the area and traffic are being diverted.

Other sources also report hearing another loud bang around the Sabon Gari area of the town close to an Evangelical Church of West Africa.

Another source later said the ECWA church was the target of the attack and that the church building was seriously damaged.

The two explosions, we are told, were followed by sporadic shootings.

Spokesperson of the Kaduna State command of the Nigerian Police Force, Aminu Lawan, confirmed the two explosions.

"Our men have been dispatched to the area, we will give you updates as soon as we confirm anything, right now investigations have commenced," he said.

We are unable to confirm casualty figures at this time as rescue agencies say they are still working to comprehend the situation. But there are fears the casualty rate would be high since it happened while Sunday service were on.

The National Emergency Management Agency has confirmed the explosions.

"Rescue and security officers have moved to the scene," NEMA spokesperson, Yushau Shuaib, said in a statement.
