Islamabad, Oct 31 (PTI) A roadside bomb targeting two vehicles belonging to security forces killed seven paramilitary troopers and injured 11 others in Pakistan's restive Khyber tribal region today.

The two vehicles were carrying rations from the northwestern city of Peshawar to troops deployed in the tribal belt.

The attack occurred 15 km from Peshawar and the bomb was triggered by remote control, officials said.

Security forces launched rescue efforts shortly after the explosion was reported.

The injured security personnel were taken to hospitals to Peshawar.

No group claimed responsibility for the attack.

Pakistani troops have been conducting operations against banned militant groups like the Lashkar-e-Islam in Khyber Agency, through which supplies are sent to US and NATO forces in Afghanistan.
