Saudi Arabian ambassador in Washington now DENIES his nation warned the United States about Tamerlan Tsarnaev in 2012
Saudi embassy in Washington D.C. issues denial of account of a senior official who talked to MailOnline
According to a highly placed source who spoke to MailOnline, the Saudis sent a written warning about Tsarnaev to the U.S. Department of Homeland Security in 2012. That was long before pressure-cooker blasts killed three and injured hundreds.
The official told MailOnline about a written warning from the Saudi government to the Department of Homeland Security, and said he had direct knowledge of that document.
But the Middle Eastern nation's embassy in Washington died that account on Wednesday.
It issued a statement which read: 'The Saudi government had no prior information about the Boston bombers. Therefore, it is not true that any information, written or otherwise, was passed to the U.S. Department of Homeland Security (DHS) or any other US agency in this regard,' an embassy statement statement claimed.
'The Saudi government also does not have any record of any application by Tamerlan Tsarnaev for any visa to Saudi Arabia.'

They've reported at the DM what the Embassy spokesperson said, but they are sticking by their report.
Daily Mail knows who this high ranking official is. And "unnamed sources" are continually cited by every media outlet.
Give me a break that an "unnamed source" discredits the story. May I remind you of "Deep Throat"?
The high-ranking Saudi official whom MailOnlne interviewed at length provided a wealth of detail about the warning he says his government sent to the United States.
He spoke on condition of anonymity because he is not authorized to talk publicly about foreign intelligence, or about Saudi ArabiaÂ’s diplomatic relationship with the United States.
He suggested that the Saudi Ministry of Interior sent the letter out of an abundance of caution in order to be helpful to the United States, even though its intelligence on Tsarnaev wasn't yet fully developed.
'With Saudi Arabia it's always code red,' he said. 'There's no code orange, or code yellow. Always red.'
The Saudi government, he added, alerted the U.S. in part because it believed American authorities should be inspecting packages that came to Tsarnaev in the mail in order to search for bomb-making components.
And they are standing by their story.
What's far fetched about this considering Russia was giving warnings as well? Or are we not to believe the stories from Russia as well?
We're only to believe "Big Sis" that this was an "action by lone wolves".
Riiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiight.
