Twitter users reportedly posted a photo of the image of the black flag of the Islamic State of Iraq and Syria in front the White House on Saturday, according to several conservative blogs and a reporter for the Dubai-based Arabic Al Aan TV.

The right-of-center blog, The Gateway Pundit reported Saturday that at least three tweets were issued over the weekend that contained the photograph of a small screen with the iconic ISIS flag in front of what appears to be the North Portico of the White House at night.

TheBlaze has been unable to independently verify the provenance of the tweets because both issuing accounts appear have apparently been suspended by Twitter.

According to a screenshot apparently captured by The Gateway Pundit however, the first tweet came from user @akhbar. The photo was accompanied by an ominous message:

“#AmessagefromISIStoUS #AmessagefromUStoISIS we are here #America near our #target :) sooooooooooooon”

Another tweet reportedly came from user @mhajr93 later in the day and included the same picture along with this message:

“we are everywhere #AmessagefromISIStoUS”

Following those tweets a number of other tweets included the image were likely copied from the original tweets. For example later on Saturday user @Sunna_rev posted the picture with the same image and yet another threatening message:

Although it is difficult to prove who exactly posted the photo to Twitter or why, the threat did appear to be in line with previous threats made by ISIS against the White House. TheBlaze reported Friday that ISIS threatened to “raise the flag of Allah in the White House.”

Additionally, The New York Daily News reported that a man associated with the militant group was apprehended at JFK Airport after an eight-month stint in Lebanon.
