The police announced the fresh explosion via its twitter handle.
The explosion came less than five hours after a blast tore through the Hotoro area of the city, killing no fewer than five persons.
The police say the second explosion was also detonated by a suicide bomber just like the first.
The number of casualty as well as other details are unavailable at this time.
