A roadside bomb Thursday killed three paramilitary soldiers in the country's restive northwest, officials said.

"Three paramilitary soldiers were killed when they walked over an IED (Impoverished explosive device) planted on a road side in Damadola area of Bajour tribal district (around 125 miles northwest of Peshawar)," local official Suhail Khan told AFP.

He said the paramilitary soldiers were returning back to their camp after a routine patrol when they stumbled over the explosive device.

Abdul Haseeb Khan, another senior official, also confirmed the incident.

Nobody immediately claimed responsibility for the attack but the Pakistani Taliban, and its splinter factions, have regularly targeted security forces in the northwest.
