PESHAWAR: At least two people were killed on Thursday when unidentified militants attacked a Nato supply convoy on the Pak-Afghan Highway in Jamrud tehsil of Khyber tribal region.

Pakistan is a key supply route for the US-led mission in landlocked Afghanistan, particularly as Nato forces prepare to withdraw troops and equipment by the end of this year.

Nato supply trucks, which carry everything from fuel to munitions and food, often come under attack on their journey between Karachi and border crossing points.

Separately, one person was killed and four others injured when militants attacked a house with a hand grenade in the Chadrar area of Tank district.

Meanwhile, militants attacked two oil tankers destroying them completely near Sur Kamar area as an exchange of firing went underway which is still continued, Khasadar forces said.

The injured include women and children.

Also, the security forces foiled a terrorism bid by defusing a five kilogram homemade bomb in a Basic Health Unit in the Pan Pao area of Shabqadar tehsil of Charsadda.
