I figure somebody, probably Mossad knew about the shipment and made a phone call to somebody, and somebody called somebody else in US intelligence.
Looks like the story broke on Saturday, May 8, and Reuters was among the first and perhaps the first to report it. But US News and Yahoo also had May 8 stories, and it appears everyone else (AP, CNN, etc) followed on Sunday, May 9, and Monday, May 10.I just find it interesting that it makes Reuters and Voice of America, but not MSM (Main Stream Media). No one that I have seen has reported it stateside. So many things over here happen that never make the media.
