Two security personnel were injured in an explosion in North Waziristan on Sunday, security officials said.

A bomb planted by the side of a road in the Kand Ghar area of Shawal exploded when a security forces vehicle passed by, officials said, adding that the bomb had been planted to target the vehicle.

The Army launched Operation Raddul Fasaad last month 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.
