The oil trailers were en route to Afghanistan for supply to NATO forces. No casualties have been reported yet.

According to police sources, an oil tanker caught fire which engulfed the other two as well.

Last week, at least two dozen oil tankers and trailers carrying supplies for NATO forces in Afghanistan were destroyed by fire after a rocket attack in the Pakistani border.
