A police officer remained unhurt in a roadside blast targeting his vehicle in Peshawar's Chamkani area on Friday, police said.

Deputy Superintendent of Police (DSP) Chamkani Abdul Salam was on a routine patrol when the remote-controlled bomb exploded near his vehicle on the Northern Bypass, Superintendent of Police (SP) rural Furqan Bilal said.

However, the police official remained unhurt, Police Control Peshawar said. His vehicle suffered minor damage in the blast in which 5 kilograms of explosives had been used.

A second remote-controlled bomb exploded in Peshawar's Karkhano Market earlier in the day moments after a police vehicle passed nearby. No loss of life was reported in this blast however, a passenger bus was partially damaged.

An official of the Bomb Disposal Unit said around 6kg of explosives packed in a pipe were planted at the roadside and detonated through a remote-controlled device.

Last month, three Frontier Constabulary (FC) officials were killed and seven others were injured in a roadside improvised explosive device (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.
