At least nine people, including three security personnel, were injured in a blast on Peshawar's Charsadda road on Tuesday, police said.
A contingent of Frontier Corps (FC) personnel was on its way from Mohmand Agency to Peshawar when their vehicle was targeted through a bomb planted on the roadside on Charsadda road, SSP Operations Sajjad Khan said.
As a result of the explosion, six civilians and three security men sustained injuries.
All the injured were shifted to Lady Reading Hospital.
Security officials cordoned off the area and started to examine the site of the blast. A search operation were also conducted in the area.
There has been no immediate claim of responsibility for the blast.
In November last year, three FC officials were killed and seven others were injured in a roadside IED blast which occurred near their vehicle in Peshawar's Bashirabad area.
The number of attacks in the country has fallen around 70 per cent, due to a combination of the military offensive against Taliban bases along the Afghan border and government initiatives to tackle militancy, but attacks on security and civilian targets continue to occur occasionally.
