Militants have attacked three NATO trucks carrying supplies for the alliance's forces in Afghanistan in the outskirts of Quetta city in southwest Pakistan, Press TV reported.
Police officials told a Press TV correspondent on Monday that the three NATO trucks were on their way from Karachi to Afghanistan through Chaman pass when militants opened fire on them. No human loss was reported.
The locals rushed to the scene and extinguished the fire, while the attackers escaped from the area. Police arrested the drivers and another suspect.
On Sunday, in a similar incident, militants set ablaze two NATO oil tankers on the outskirts of Quetta, the capital of the southwestern province of Balochistan.
No group has claimed responsibility for the attacks.
Suspected pro-Taliban militants frequently attack oil tankers and trucks transferring goods from the port city of Karachi to NATO bases in Afghanistan.
