The US bluntly told Pakistan to ensure that no terrorist or militant groups are allowed to continue within its territory and to make sure that no support is being given to them by the government there. Deputy National Security Advisor John Brennan told this to the Fox News in an interview. The top White House counter-terrorism official said there are evidences of involvement of Pakistani Taliban in the failed Times Square plot for which Pakistani-American Faisal Shahzad was arrested recently. They added it looks as though he was operating on behalf of the Tehrik-e-Taliban Pakistan.Echoing similar sentiments, US Attorney General Eric Holder told a television channel that Faisal Shahzad was working at their direction. Mr Brennan said, Pakistan Taliban is closely allied with Al Qaida. It has a murderous agenda similar to Al Qaida. They train, plan and plot together. They're almost indistinguishable. The tough message came a day after Secretary of State Hillary Clinton warned Pakistan that it will face very severe consequences if any terror plot was traced to that country.
