NORA O'DONNELL: And tonight, we're learning new details about the US airstrikes against Iranian-backed militia groups in Syria. A short time ago, President Biden told reporters he's putting Iran on notice, that it can't act with impunity in the Middle East, and to be careful. CBS's David Martin reports tonight from the Pentagon.

DAVID MARTIN: Cell phone video shows what was left of a desolate outpost on the Syrian side of the border with Iraq. Two F-15 Eagles dropped seven 500-pound bombs, completely destroying nine buildings and damaging two. Initial reports said one person was killed and three injured.

JOHN KIRBY: We recognize the significance of this operation as the first of its kind under the new administration.

DAVID MARTIN: Pentagon Spokesman John Kirby said the Iranian backed militias used the border post to smuggle weapons into Iraq.

JOHN KIRBY: We had information that these structures, this site, this compound, were being used by these groups to facilitate the movement of resources, material, and weaponry into Iraq to conduct the attacks.

DAVID MARTIN: Two weeks ago, US officials say Iranian-made rockets were fired at a base in Iraq where American troops are located. Last night's strike was a message to Iran.

JOHN KIRBY: That is an unambiguous, clear message to anyone in the region about what the stakes are if you're going to continue to conduct attacks on our people.

DAVID MARTIN: Defense officials say this strike was intended as a one and done, but that will depend on how Iran and its allies react. David Martin, CBS News, the Pentagon.
