US President Barack Obama expects two initial security reviews will be completed this week following a failed attempt last month to destroy a Delta Air Lines Airbus A330.
The president ordered a review of all air travel screening policies, technologies and procedures and a review of the nation's terrorist watch system after Umar Farouk Abdulmutallab reportedly attempted to detonate an explosive device on the aircraft during approach to Detroit from Amsterdam on 25 December.
As the reviews near completion this week, Obama also says his administration plans to publish a summary of preliminary results from those examinations within the next few days.
"This was not a failure to collect intelligence. It was a failure to integrate and understand the intelligence we already had," Obama told reporters today after a meeting with intelligence officials, including representatives from the US Department of Homeland Security.
Previously Obama has admitted that members of the US intelligence community received information from the suspect's father on Abdulmutallab's extremist views, but that information was not effectively distributed to ensure his name appeared on a no-fly list.
After the failed attack, the US government required new screening and security procedures for all domestic and international flights, and an increase in the number of federal air marshals on flights leaving and entering the USA.
Following those actions the US Transportation Security Administration (TSA) on 4 January mandated new security measures covering inbound flights from or through 14 nations that are either state sponsors of terrorism or other countries of interest. The directive also increases the use of enhanced screening technologies, and mandates threat-based and random screening for passengers on international flights bound for the USA.
