The bomb went off at around 10 am injuring three passers-by by its splinters. They were immediately taken to a nearby private hospital where their condition was stated to be out of danger.
According to preliminary police report, the bomb might have been planted in the wee hours by suspected militants to attack security personnel who used to pass through the area regularly. Police and paramilitary forces surrounded the area minutes after the blast and launched search operation after blocking all exit points but no arrest is made so far.
It is not yet known whether the militants used remote-controlled device or timer to explode it. No individual or group has claimed responsibility so far.
