Rep. Michael McCaul said the Department of Homeland Security issued a bulletin to airlines flying into Russia warning of the potential threat.
The bulletin, the Texas Republican said, indicated that officials believed the explosives might be used during flights or smuggled into the city of Sochi, where competition at the Winter Olympics begins Thursday. The opening ceremony is Friday.
A U.S. law enforcement official told CNN that the cause for the Homeland Security alert was specific to the imminent start of the Games.
According to the source, authorities have increasing confidence about the safety of Sochi and the Olympic venues. Still, U.S. intelligence is picking up increasing chatter that causes worry about targets outside of the Sochi area, including regional transportation links.
Any C4 will be "Made in US" or "Made in Israel", that must have been "stolen" from military storage, and the "suicide bomber" will not know what is in luggage, and he will be of Arabic descendant.
That is very obvious.
"On April 20, I was on duty at Kabul airport customs terminal; I witnessed a British intelligence officer who, along with three British militaries tried to get away with a rather large box delivered to Kabul by ISAF plane, with no customs inspection. I knew this officer by sight since he was a frequent visitor at Kabul airport. I asked the British military to show their cargo documents; they refused to do it. When I persisted in my request, they said I had no right to demand anything from them since they enjoyed diplomatic immunity. When I told them my boss's order bans me from allowing cargo out without examination, a squabble emerged between us. I ordered my assistants never permit the British vehicle out of the terminal gates until I contacted my boss. At this moment, one of the British militaries put his gun against the chest of a police officer in an attempt to open the gates. The other police officer seized the box handle and pulled it. The box fell on the ground and flung open. I was amazed to discover that it contained at least 15 and maybe even 20 "belts" for suicide bombers.
