The bombers targeted a second hotel, the Aden Movenpick, where they believed American troops might also be staying. That bomb detonated prematurely in the hotel car park, around the same time as the other bomb explosion, killing two Australian tourists. Bin Laden later claimed that he and Mohamed Khan were responsible for the 1992 Yemen attack.

The third was crashed into the Pentagon and the fourth in a field during a struggle between passengers and hijackers to control the airplane. An investigation conducted after the attacks concluded that members of al-Qaeda planned and orchestrated the attacks.

Shortly after the arrest of Umar Farouk Abdulmutallab in the December 25, 2009 bombing attack on Northwest Airlines Flight 253, the suspect reportedly told officials he had traveled to Yemen for training by Al-Qaeda, although British counterterrorism officials dismissed the claims. President Barack Obama's top security official Janet Napolitano on December 27 stated "Right now we have no indication it's part of anything larger", warning it would be "inappropriate to speculate" that Al-Qaeda had sent Abdulmutallab on a suicide mission. On December 28, President Obama called it an "attempted terrorist attack" and promised to "to use every element of our national power to disrupt, to dismantle and defeat the violent extremists who threaten us, whether they are from Afghanistan or Pakistan...". That same day, Al Qaeda in the Arabian Peninsula claimed responsibility for the attack. The group released photos of Nigerian Umar Farouk Abdulmutallab smiling in a white shirt and white Islamic skullcap with the Al Qaeda in Arabian Peninsula banner in the background. On January 8, 2010, President Barack Obama took responsibility for security lapses exposed by the attack, declaring in televised remarks "We are at war against Al-Qaeda", noting "our adversaries will seek new ways to evade them, as was shown by the Christmas attack" By February 2010, the suspect told federal investigators that cleric Anwar al-Awlaki gave him orders to carry out the attack. Al-Jazeera reported that Awlaki issued a statement that "Brother mujahed Umar Farouk – may God relieve him – is one of my students, yes... We had kept in contact, but I didn't issue a fatwa to Umar Farouk for this operation,".
