US officials believe Iran was behind a drone attack that occurred last week at the military outpost in southern Syria where American troops are based.

key notes

Officials said Monday the US believes that Iran resourced and encouraged the attack.

They were Iranian drones, and Iran appears to have facilitated their use.

Officials believe the attacks involved as many as five drones laden with explosive charges, and that they hit both the US side of al-Tanf garrison and the side where Syrian opposition forces stay.

Market implications

There has been no reaction, thus far, to this developing situation but what is important, for now, is that there were no reported injuries or deaths as a result of the attack.
