Islamabad, May 26 (TIWN) After the Pentagon official claimed that Pakistan has allowed the US to use its airspace and ground routes as part of its Afghanistan campaign, a debate is underway in Islamabad regarding giving such an access to the US.

In Pakistan, allowing access to airspace and ground routes to the US would be a costly mistake as it would have serious repercussions on Pakistan's national security.     Zahid Hafeez Chaudhri, Pakistan foreign office spokesperson, said in a statement on Monday: "There was no US military or air base in Pakistan, nor was any such proposal envisaged," adding that any speculation on the topic was "baseless, irresponsible and should be avoided".  Since 2001, Pakistan and the US have had a framework of cooperation for Air Lines of Communication and Ground Lines of Communication, but "no new agreement has been made in this regard", the statement added.
