US Secret Service have suddenly evacuated White House reporters and directed them to the situation room of the building.
CNBC reporter said Megan Cassella said: "U.S. Secret Service just evacuated us from our camera position at the White House north lawn. We’re now gathering in the briefing room. No indication as to what’s going on."
Reports on social media claim gunfire has been heard near the White House, but this is yet to be confirmed.
