A missile attack targeted on Saturday the US occupation base in Al-Omar oil field in the Deir Ezzor countryside, local sources told the Syrian news agency SANA.

"A missile attack targeted on Saturday Al-Omar oil field, which the US occupation forces take as an illegal base for them in the eastern countryside of Deir Ezzor, no information whether there were any casualties among the occupation forces,' the sources told SANA.

Al Mayadeen correspondent in Syria said the missile attack targeted the US forces' helipad.

In late December, Syrian media reported that the base was shelled with several missiles.

Al-Omar oil field is the largest Syrian oil field. The US is currently occupying the oil field, and has  repeatedly looted Syrian oil to the tune of billions of dollars.

The US army and other foreign forces participating in the so-called "international coalition" occupy at least 28 declared military sites in Syria, distributed over three provinces, namely Al-Hasakah (17 sites), Deir Ezzor (9 sites), and Homs (2 sites).

What is the US doing in Syria?

It is noteworthy that Syrian state media has accused the US and the so-called Syrian Democratic Forces (SDF) of occupying areas in the vicinity of oil-rich fields and smuggling resources to Iraq.

Convoys of tens of vehicles, including tankers loaded with stolen oil from oil fields occupied by US forces in Syria, are frequently seen crossing toward northern Iraq, in addition to trucks loaded with military equipment.

The US has supported SDF militias against Damascus for years, and the US-backed forces are currently occupying parts of the provinces of Al-Hasakah, Deir Ezzor, and Al-Raqqa, where the largest Syrian oil and gas fields are located.
