Five people were killed and 15 others wounded Tuesday night when Taliban launched an attack on a stopped logistic convoy in western Afghan province of Farah, the authorities said Wednesday morning.

"The militants launched attack on a parking lot where dozens of logistic trucks were stopped in Bala Buluk district at round 8:30 p.m. local time Tuesday. They used heavy weapons and rocket propelled grenades (RPGs) in the attack. As a result five people were killed and 15 were injured," a provincial police spokesman Najib Afghan told Xinhua.

He said 25 trucks, including several oil tankers, were torched and completely destroyed in the attack which took place in Farahrod area, located along the Kandahar-Herat highway.

One Public Protection Police Force (PPPF) cop was among the killed and others victims were drivers and their helpers in the incident in the province, some 695 km west of national Kabul.

The PPPF police force is in charge of providing security for convoys and development projects across the war-hit country. It replaced the local and foreign private security companies after the government dissolved private security firms in recent years.

Last week, more than 70 militants and 11 PPPF personnel were killed and 20 policemen were injured in similar incident in Farah' s Gulistan district.

The Taliban-led insurgency has been rampant since the militant group launched annual rebel offensive in April against Afghan government forces and about 98,000 NATO-led troops stationed in the country.

The Taliban urged civilians to stay away from official gatherings, military convoys and centers regarded as the legitimate targets by militants besides warning people not to support the government and foreign troops.

In an unrelated development, two civilians were killed when Taliban fired nine rockets on the administrative district compound in Dangam district of eastern Kunar province, 185 km east of Kabul also Tuesday night.
