US President Barack Obama has said that a systemic failure occurred in the intelligence network ahead of the thwarted attack on a US-bound flight from Amsterdam on Christmas Day. Terming this unacceptable, he asked the authorities to submit a preliminary report on the failed attempt by a Nigerian national to blow up a North West Airlines plane with 300 passengers on board. President said this in his remarks to the press at Hawaii, where he and his family are on year-end vacation. Umar Farouk Abdulmutallab from Nigeria has been charged by the federal authorities with attempt to blow up the plane. Al-Qaeda has claimed responsibility for the attempted attack. Obama said, it now appears that weeks ago this information was passed to a component of our intelligence community, but was not effectively distributed so as to get the suspect's name on a no-fly list. On Monday, Obama had issued instructions to review the terrorist watch list system and air travel screening.
