The US has asked Pakistan to take decisive action against terrorists within its borders. Itfirmly said, Pakistan spy agency ISI must strategically shift its focus as any ties with terror outfits that has come to light is unacceptable. The American prescription in the war against terrorism came even as US President Barack Obama reviewed the current situation in Afghanistan and Pakistan, along with the recently held US-Pak Strategic Dialogue in Islamabad, at his monthly situation room meeting with his top national security aides. State Department spokesman P J Crowley told reporters at his daily news conference that the Obama Administration voiced concern about the contacts by some elements in ISI with terror outfits in the wake of the leak of military documents by WikiLeaks that laid bare its links with terror outfits in Afghanistan.
