The United States is now focusing on investigations into Times Square bomb suspect Faisal Shahzad's terror links in Pakistan, following his revelation that he attended a terrorist training camp in Waziristan.
"A big part of that ongoing investigation is to evaluate where he was and what he was doing during his time in Pakistan. Beyond that, I don't want to get into a lot of specifics on that at this point," White House spokesman Robert Gibbs told reporters at his daily press briefing.
Without going into specifics, Gibbs said Justice Department and investigating agencies are actively looking at the time, which Shahzad spent in Pakistan.
"He has admitted in the charging documents, in the complaint that he went to terrorist training in Waziristan" New York Police Commissioner Raymond Kelly told the Charlie Rose Show on PBS in an interview.
Kelly also said that a team was dispatched to talk to people in Karachi, where several people have been arrested in connection with the Times Square case.
"There is a link to Pakistan," Kelly said, adding that Shahzad has acknowledged about his bomb-making training in Waziristan.
"My guess is you got policemen on their way to Karachi right now who want to talk to the people there," Kelly said.
He said that family members of Shahzad were still in Pakistan and not coming to the United States.
Meanwhile, the Fox news reported that the Times Square bomb suspect was upset with the drone attacks.
In his last trip to Pakistan, Fox News quoting Pakistani officials said that Shahzad was introduced to Qari Hussain, the Number 3 in the top tier leadership of the Pakistani Taliban.
