ISLAMABAD - Pakistan has sent a letter to the US Embassy in Islamabad, asking it to phase out over 250 US officials in 30 to 40 days, a private TV channel quoting sources reported Tuesday. It said US Ambassador Cameron Munter is coming back to Pakistan after cutting short his holidays to deal with the emerging situation. Pakistan and the United States have been at odds over the appointment of US contractors and their visas had been drastically cut down. Pakistan has also restricted movement of all foreign diplomats in the country following the unilateral Abbottabad raid by US special forces to kill Osama bin Laden. The United States has already applied heavy-handed methods in dealing with the key ally in the war on terror. The US has stifled CSF funding in such a way that Pakistan awaits its own money to be reimbursed for the logistic and other support the country has been extending to the 'friend US in the war on terror. APP adds: US Embassy has rejected the news item about notices given to its diplomats to leave Pakistan. A US Embassy Spokesperson while commenting on the news regarding notices issued to 250 US officials to leave Pakistan within one month said, It is untrue.
