The US has said President Barack Obama's meeting with Pakistan Prime Minister Nawaz Sharif at the White House last week did not set a timeline for actions against terrorist outfits like Lashkar-e-Taiba (LeT).


"We're not dictating to Pakistan the timeline under which they would or would not undertake operations against that or any other terrorist group," State Department Spokesman John Kirby told reporters at his daily news conference.


"We know that they know that these are serious threats, we know that they know how much it matters not just to the region but to the world. And it's a difficult problem to crack," he said.


In response to a question on an interview given by the former Pakistan president Pervez Musharraf in which he said that Pakistan supported and aided terrorist organisations like LeT, Kirby said, "I didn't see the former President's comments."


"All I would say is that we have a shared concern with Pakistan about violent extremism in that part of the world. Two, we know that safe havens still exist along that border region and we've been very plain about our concerns over those continued safe havens," he said.
