ABC News's Diane Sawyer asked James Clapper, the USA's Director of National Intelligence, about the arrest of the twelve terror suspects in the UK.
Clapper "responded with stunned silence".
National Security Advisor John Brennan later admitted that Clapper, the head of the sixteen US intelligence agencies, had not been told about the arrests.
"First of all, London," ABC's Sawyer asked. "How serious is it? Any implication that it was coming here? ... Director Clapper?"
"London?" Clapper said after a pause.
On 20 December 2010, British police detained 12 'suspected terrorists' as a result of INTERPOL warnings of possible Christmas bomb attacks.
The suspects, mainly from Bangladesh, were detained in London, Birmingham, Cardiff, and Stoke on Trent.
Interpol had issued a bulletin claiming that it "received information... from the Interpol office in Baghdad about possible threats, especially in the U.S. and Europe, due to orders given to al-Qaeda (CIA) cells by al-Qaeda (CIA) commanders."
How might the security services recruit 'false flag terrorists'?
Three of the men arrested in Cardiff had previously been convicted of theft and drugs offences.
In prison they might make ideal recruits as double agents and patsies?
The UK's MI6 chief, Sir John Sawers. Does he know what is going on?

The forests around Ross Priory are sometimes used by the military.
Ross Priory Wood recently had an explosion blamed on al Qaeda.
Ross Priory is in the Gartocharn region.
An army veteran writes:
"Why didn't the local farmers in the Gartocharn region know that there were 'interlopers' on their land?
"This area, of which I know full well, incorporates the lands of one of Scotland's most decorated Soldiers, Brigadier Pearson, and ALSO borders the grounds of a close 21 SAS friend of mine who has 'stables' nearby."
"Starting from at least the 1980's, SAS and British military intelligence agents were routinely ordered to embed themselves within violent branches of the IRA and aid terrorists in carrying out attacks.
"How do we know this happened? Because one of the individuals who was ordered to do so, Kevin Fulton, blew the whistle on the fact that he was told he had the Prime Minister's blessing to aid terrorists in bomb making and political assassinations."
