Five people were killed on Monday in a bomb blast in Khyber Agency's Tirah valley, security sources said.
The remote-controlled bomb went off near a vehicle of a peace committee killing five volunteers in Tirah valley's Akakhel area, security sources added.
Rescue teams and security forces arrived at the scene shortly after reports of the bombing, security sources said.
The Army had launched Operation Raddul Fasaad in February following a spate of terror attacks in the country, which claimed more than a hundred lives and left hundreds others injured.
The operation seeks to eliminate the "residual/latent threat of terrorism", consolidating the gains made in other military operations, and further ensuring the security of Pakistan's borders.Hundreds of suspected terrorists have reportedly either been killed or arrested in raids carried out by security personnel since the start of the operation.
