United States Secret Service is investigating a photograph blasted out on Twitter which seems to show someone holding up a smartphone, displaying a picture of the ISIS flag, in front of the White House.
The photo appears to have been taken at night on the pedestrian mall occupying what used to be part of Pennsylvania Avenue. The White House's north portico can be seen in the background.
It was first tweeted on August 9 by an account that was later deleted.
'[W]e are here #America near our #target :) sooooooooooooon,' read the message that accompanied it.
