The United States has stepped up efforts to prevent people on "no-fly" lists from boarding flights after the suspected New York car bomber was allowed to board a flight to Dubai.
Faisal Shahzad, accused of trying to bomb Times Square, was arrested on May 3 on a plane preparing to take off for Dubai despite having been placed on a "no-fly" list.
U.S. aviation officials reportedly said they had beefed up security requirements for passengers, demanding airlines check "no-fly" lists within two hours of learning of a suspect name, instead of the previous requirement of 24 hours.
According to the charges filed by U.S. prosecutors, Shahzad, 30, has told investigators that he recently received bomb-making training in the Waziristan region of Pakistan, not far from the Afghan border.
Officials say they are continuing to probe whether Shahzad is affiliated with a militant group and whether there is a foreign link to the bomb plot.
