Pakistan has imposed curbs on the movement of US diplomats and other embassy staffers in the country. Geo TV reported quoting unnamed sources that all US diplomats will now require to get special – No Objection Certificate – for travelling to other cities. But there was no official word and reaction from the US embassy in Islamabad. The reports came at a time when relations between the US and Pakistan have deteriorated after the this month blockade of 800 US dollar military aid.
