Sources in Syria told Al-Mayadeen that on the evening of 22 October, an unidentified drone, along with several rockets, targeted the headquarters of the US military base in the Al-Omar oil field in Deir Ezzor, eastern Syria.

The same sources indicated that explosions were heard from inside the US base.

Following the attack, the US-led coalition activated army helicopters and reconnaissance drones around the area, in an attempt to detect and identify the source of the attacks.

The UK-based Syrian Observatory for Human Rights (SOHR) monitored at least five explosions that struck the Al-Omar oilfield for unknown reasons.

However, activists on social media said four missiles targeted the US base in the Al-Omar oil field, which is on the border with Iraq.

So far, no group has claimed responsibility for the attack.

Others indicated that the coalition forces responded by bombing the agricultural forests on the outskirts of Al-Mayadeen city in Deir Ezzor. 

A day earlier, Israeli jet fighters launched a new round of airstrikes on the surroundings of the Syrian capital Damascus, which were successfully thwarted by Syrian air defense systems, as they “intercept[ed] most of the incoming missiles,” according to state media.

More often than not, Israeli attacks on Syria tend to be followed by unidentified targeted attacks on the illegal US bases in Syria’s oil-rich Jazira region.

The US army and the international coalition occupy at least 28 declared military sites in Syria, distributed over three provinces, mainly Hasakah (17 sites), Deir Ezzor (nine locations), and Homs (two areas).

The last targeting against the illegally occupying forces in the Al-Omar oil field was conducted in September, resulting in zero casualties and no comment from Washington.

In a similar scenario, on 8 October, the United States Central Command (CENTCOM) said the Rumalyn landing zone, one of its bases in the far east of Hasakah, was subjected to a missile attack that did not cause any casualties.

According to the Syrian authorities, the US occupation forces and their mercenaries steal up to 66,000 barrels per day from the fields they occupy in eastern Syria.
