President Obama was told Tuesday about more missed signals and uncorrelated intelligence that should have prevented a would-be bomber from boarding a flight to the United States, leading the president to declare that there had been a “systemic failure” of the nation’s security apparatus.
Two officials said the government had intelligence from Yemen before Friday that leaders of a branch of Al Qaeda were talking about “a Nigerian” being prepared for a terrorist attack. While the attacker was not named, officials said it would have been evident had it been compared to information about Umar Farouk Abdulmutallab, the 23-year-old Nigerian charged with trying to blow up an American passenger jet on Christmas Day.
The government also had more information about where Mr. Abdulmutallab had been and what some of his plans were before boarding the Northwest Airlines flight to Detroit. Some of the information was partial or incomplete at the time, and it was not obvious that it was connected, one senior administration official said, but in retrospect it now appears clear that had it all been examined together it would have pointed to the pending attack.
