A MAN who attempted to light an explosive aboard a US airplane as it landed in Detroit on a flight from Amsterdam says he is affiliated with al-Qaeda.
CNN, citing a federal bulletin, said the man told investigators he had acquired the explosive in Yemen, along with instructions as to when it should be used.
It was initially believed the man had set off firecrackers.
President Barack Obama, who is vacationing with his family in Hawaii, was notified about the incident and held a conference call with his national security team, the White House said.
