The undercover informant in the foiled underwear bomb plot linked to al Qaeda's Yemeni affiliate was a British citizen, possibly of Saudi origin, US counter-terrorism officials said.
British intelligence played a central role in the operation that foiled the plot to send a suicide bomber onto an airplane, and it was a cooperative effort between MI5 and MI6, Britain's domestic and foreign intelligence services known, officials told Reuters on condition of anonymity.
An undercover agent who foiled an al-Qaeda plot to blow up an airliner with an underwear bomb is a British national.
It seems the man who foiled al-Qaeda's latest underpants bombing plot was a Saudi intelligence agent.
Ibrahim Hassan al-Asiri is the man the FBI think is behind the latest al-Qaeda terror threat to come out of Yemen.
