"While there are no immediate threats to the District of Columbia, we remain vigilant and MPD & HSEMA will remain in close contact with regional and federal partners to monitor evolving events — both at home and abroad. As always, we remind members of the public if they see something, say something by contacting law enforcement of any suspicious activity." -- D.C. Mayor Bowser

Iran vowed "harsh retaliation" for the killing of Gen. Qassem Soleimani, the head of Iran's elite Quds Force and the architect of its interventions across the Middle East.

The United States urged American citizens to leave Iraq "immediately" following the Friday airstrike at Baghdad's international airport that killed Soleimani and nine others.

The State Department said the embassy in Baghdad, which was attacked by Iran-backed militiamen and their supporters earlier this week, is closed and all consular services have been suspended.
