Update(1337ET): The White House is addressing viral video which purported to show a military helicopter on top of the US Embassy in Baghdad following Iraqi protesters breaching the high-secure Green Zone.

"Reports of an Embassy evacuation are false. Ensuring the safety of US government personnel, US citizens, and the security of our facilities remains our highest priority," a White House official said in the hours after the security situation unraveled. The official called reports of violent confrontation with police "disturbing" after a curfew for the Iraqi capital went into effect.

"Now is the time for dialogue, not escalated confrontation," the official said. "We join the call by parties across the Iraqi political spectrum to remain calm, abstain from violence, and resolve their political differences through a peaceful process guided by the Iraqi constitution."
