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 female suicide bomber just like the first.

“One female suicide bomber about 18yrs died, 6 persons injured,” the police announced.

There is panic across the city and sorrow is etched on the faces of residents, our correspondent says.
