At least three Frontier Corps (FC) personnel and one civilian were injured in an Improvised Explosive Device (IED) blast on Quetta's Sariab Road on Wednesday morning, police sources said.

The bomb, which was planted on the roadside, targeted an FC vehicle while it was on patrol. The explosion left the vehicle partially damaged.

Police and FC personnel reached the site after the blast and started an investigation. The injured was shifted to a nearby hospital.

Traffic was suspended in the area following the incident and security was tightened.

There has been no immediate claim of responsibility for the blast.

Pakistan is experiencing a fresh resurgence in terror attacks.

Last month, over 100 people were killed in terror attacks in Sindh, Balochistan, KP, Fata and Punjab.

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.
