Suspected militants in Rawalpindi have set fire to at least fifteen coalition forces trucks, transporting oil and other essentials to US-led forces in Afghanistan.

The Tuesday attack in Tarnol, Rawalpindi, in the Punjab province, was the first reported case to have taken place in Rawalpindi.

Most of the previous attacks have taken place in Quetta and other places close to the Afghan border.

The latest attack puts into question the security situation in the nation’s capital, Islamabad which is close to the garrison city of Rawalpindi.
