There is nothing in the response of the US State Dept. spokesperson which can be treated as warning...
'our friends in Pakistan'(Musharraf) 'media has a responsibility to report the news accurately and objectively'(i.e., in favour of US interests => Musharraf) 'needed to be resolved by the Pakistanis themselves within the confines of the country's laws and judicial process'(made by Musharraf)
...such statements are in favour of Musharraf. I dunno how rediff can select such a heading for this article. It should be like "US stays neutral on media curbs in Pak"
