On August 8, 2014, All News PipeLine published an article reporting that ISIS had threatened America stating "God willing, and we will raise the flag of Allah in the White House." Well, they just did, not inside the White House, but directly outside the White House, taken "taken at night from the Pennsylvania Avenue side," as reported at Gateway Pundit.
They posted this photo twice, first with the message "“we are here #America near our #target :) sooooooooooooon," then a second time with the message "we are everywhere." Both had the hashtag #AmessagefromISIStoUS.
The following morning, a third message appeared, "We are in your state. We are in your cities. We are in your streets. You are our goals everywhere."
Screen shots of all three messages will be shown below the video.
