US Secretary of State Hillary Clinton has called on Pakistan to take "strong steps" to deny Afghan insurgents sanctuary on its soil.
Speaking in Islamabad after talks with Foreign Minister Hina Rabbani Khar, she also urged Pakistan to encourage the Taliban to enter talks "in good faith", BBC reported.
Mrs Clinton is delivering a blunt message that Pakistan must step up its counter-terror efforts.
Relations between the US and Pakistan are at their lowest point for a decade.
After months of tension, Mrs Clinton is heading a high-powered delegation that includes CIA chief David Petraeus and the new Chairman of the Joint Chiefs of Staff, Gen Martin Dempsey.
On Thursday she called for a new partnership between the US, Afghanistan and Pakistan to fight militants.
She said Pakistan "must be part of the solution" to the Afghan conflict.
