PESHAWAR: A number of vehicles were destroyed on Thursday when unidentified men attacked a terminal in the Gumrak village of Jalalabad city in Afghanistan from where Nato supply trucks cross.

Subsequently, the Torkham crossing was closed for traffic and security was beefed up near Pak-Afghan border.

The attack comes days after the Pakistani military launched a full-scale military operation in the North Waziristan tribal region which has been regarded as a haven for militants from various groups, including the ones orchestrating attacks on government and US interests in Afghanistan.

No group has admitted responsibility but the Taliban have in the past claimed such attacks to disrupt supplies for the US-led international troops fighting in Afghanistan.

Taliban and Al Qaeda-linked militants frequently launch attacks across northwest Pakistan and the lawless tribal belt.

From November 2011 to July 2012, Pakistan shut its Afghan border to overland Nato traffic after botched US air raids that killed 24 Pakistani troops.
