The second blast targeted the Kawo area of the troubled city.
A second explosion has hit Kaduna town, barely two hours after a blast killed at least 25 people.
A witness said there were many bodies at the scene of the second attack which occurred at the busy Kawo bus stop within central Kaduna.
The first blast targeted at a prominent Islamic cleric, Dahiru Bauchi.
One witness said the second bomb was concealed in a Golf car, just as the first.
“There are also many casualties at the moment and the police have cordoned the area with both rescue team and the police evacuating injured victims,” a witness said.
