Attacker not on 'no fly' list
Washington - Al-Qaeda involvement is a "subject of investigation" in Friday's incident in which a Nigerian man has been charged with trying to blow up a US passenger jet bound from Amsterdam to Detroit, US homeland security chief Janet Napolitano said on Sunday.
Presidential spokesperson Robert Gibbs, appearing on ABC's This Week, also said the White House is reviewing US security watch list policy.
The US government created a record of 23-year-old Umar Farouk Abdulmutallab last month in the intelligence community's central repository of information on known and suspected international terrorists, a US official said on Saturday. But there was not enough negative data to put him on a "no-fly" list, the official said.
Asked whether al-Qaeda was involved in the incident, Napolitano also told ABC's This Week programme, "That is now the subject of investigation, and it would be inappropriate for me to say and inappropriate to speculate. So we will let the FBI and the criminal justice system now do their work."
Gibbs said the administration was reviewing "how can we revise watch-listing procedures going forward to ensure that there is no clog in the bureaucratic plumbing of information that might be gathered somewhere going to the very highest levels of security in government."
