The US Defence Secretary Leon Panetta has said the leaks to the press about the identity of the undercover agent who foiled an al-Qaeda plot to blow up an underwear bomb were dangerous, and would be investigated.

Speaking to reporters at a press briefing at the Pentagon he said:

"The whole effort is to be able to try to get individuals who can provide intelligence and work with us, and to be able to do that, and to do that effectively you have to be able to protect these people"

"When these leaks take place, I can't tell you how much they damage our ability to be able to pursue our intelligence efforts"
