Jordanian Minister of Government Communications Muhannad Mubaidin said Sunday that the attack targeting U.S. forces near the Syrian border did not occur inside Jordan.
Mubaidin told the state-run Al Mamlaka TV that the attack targeted the al-Tanf base in southeastern Syria.
This means that the attack is on an illegal US base in Syria, right on the border with Jordan.

What I posted are two separate accounts. The US claims the base was in Jordan and Jordan says the base was in Syria. The reason US does not want to admit the base in Syria is because US is occupying Syria in defiance of international law, and has no legal basis for its presence there. Hope that clears things up for you.
