US Special Envoy for Afghanistan and Pakistan Richard Holbrooke on Friday expressed satisfaction at Pakistan's military operation against the Taliban in the Swat and nearby areas and said Washington would respect "red lines" marked by Islamabad in the war against terror.
Addressing a news conference at the US embassy here at the conclusion of his three-day visit to Pakistan, Holbrooke acknowledged that Pakistani troops have turned the corner in their operations against the Taliban and cleared several areas, including Mingora and Buner, of militants.
The US has seen the seriousness and dedication of the Pakistan Army in the military operation, he said, adding Islamabad was firmly committed to the return of millions of displaced people to Malakand, which has seen a "sustained anti-Taliban drive".
Referring to the "red lines" laid down by Islamabad, Holbrooke said US forces would not enter Pakistani territory and would respect the country's sovereignty and integrity.
Pakistani troops are responsible for taking action against terrorists on their soil, he added.
Holbrooke admitted the proposed US military surge in Afghanistan could have a spill-over effect in Pakistan.
However, the US and ISAF forces in Afghanistan, operating close to the border with Pakistan, will take this issue into account, he said.
