WASHINGTON — A man who attempted to light an explosive aboard a US airplane as it landed in Detroit on a flight from Amsterdam told investigators he was affiliated with Al-Qaeda, US media reported Friday.

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.

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, CNN reported.

Sandra Berchtold, an FBI spokeswoman in Detroit, told AFP the incident was under investigation.
