At the start of Operation Inherent Resolve (OIR), the coalition found itself in a confrontation with Syrian pro-government militias and Russian private military contractors. This conflict was triggered by an assault on the Syrian Democratic Forces (SDF) near Khasham, which soon intensified into the Battle of Khasham.
Although heavy gunfire continued, U.S. forces were able to withdraw without sustaining any casualties, which drew media attention as “the first deadly clash between citizens of Russia and the United States since the Cold War.”
Operation Inherent Resolve (OIR) began in 2014
In the fall of 2014, the United States commenced its military involvement in Syria under Operation Inherent Resolve, targeting the Islamic State of Iraq and the Levant (ISIL). By 2017, with support from the US military, the Syrian Democratic Forces seized Raqqa and advanced towards the Euphrates River. During this period, a deconfliction line was established through collaborative efforts between the US and Russian authorities.
Since 2015, Russia has been actively carrying out aerial missions in Syria to support the government. Additionally, Russian private military contractors associated with the Wagner Group have been operating in the region. However, the Russian government has not officially recognized their participation in ground operations.
A growing presence of militia fighters
Additionally, the outpost received crucial support from US Marines and Green Berets stationed 20 miles away, who supplied essential reconnaissance and surveillance information.
On February 7, 2018, these troops found themselves encircled by more than 500 pro-government militia, supported by T-72 and T-55 tanks. Early intelligence from drone surveillance provided critical advance warning, enabling them to assemble a rapid-response team in preparation for any potential conflict.
Battle of Khasham commences
At around 10:00 PM that evening, the Russian and Syrian militia began their assault on the outpost.
Using artillery and mortar rounds in what the US officials called an “uncoordinated attack,” the American soldiers retaliated by firing Javelin anti-tank missiles. As The New York Times reported, “The air was filled with dust and shrapnel. […] For the first 15 minutes, American military officials called their Russian counterparts and urged them to stop the attack. When that failed, American troops fired warning shots at a group of vehicles and a howitzer.”
Prior to the eruption of the Battle of Khasham, military officials at the Combined Air Operations Center in Qatar had spotted the growing Russian and pro-government force and quickly deployed air support.
“American warplanes arrived in waves, including Reaper drones, F-22 stealth fighter jets, F-15E Strike Fighters, B-52 bombers, AC-130 gunships and AH-64 Apache helicopters,” The New York Times wrote. “For the next three hours, American officials said, scores of strikes pummeled enemy troops, tanks and other vehicles. Marine rocket artillery was fired from the ground.”
Late arrival of the quick response forces
The Battle of Khasham had run for about three hours before the quick response force of Marines and Green Berets finally arrived. The drivers had to rely on night vision equipment to navigate the dark terrain, as they didn’t want to give away their approaching position with their headlights.
Additionally, the roads they’d traveled were “littered with felled power lines and shell craters.” In fact, halfway there, the force had to stop as “the barrage of artillery was too dangerous to drive through until airstrikes silenced the enemy’s howitzers and tanks,” The New York Times reported.
The QRF finally arrived at 1:00 AM, just as the enemies’ vehicles were burning and they were transitioning to an on-foot attack.
Aftermath of the Battle of Khasham and transparency
The Battle of Khasham wrapped up shortly after the enemy retreated. In this intense clash, no American troops were injured, while the enemy suffered considerable losses, with an estimated 200-300 fighters killed.
In response, US officials were open about the situation, clarifying that pro-government forces, in collaboration with the Russians, initiated the attack on the Syrian Democratic Forces while the American forces were positioned east of the Euphrates deconfliction line.
The Russian Ministry of Defence released a statement about the battle, stating that the conflict arose due to unauthorized reconnaissance by Syrian militias, which had not been approved by the Russian operations command, and that no Russian service members were present in the designated district of Deir ez-Zor province.
US officials kept in constant contact with the Russians
After the Battle of Khasham, Lt. Gen. Jeffrey L. Harrigian, commander of the US Air Forces Central Command, noted that before the clash, “The coalition observed a slow buildup of personnel and equipment the previous week, and we reminded Russian officials of the SDF and coalition presence via the telephone deconfliction line. This was well in advance of the enemy forces’ attack.”
Throughout the confrontation, US officials maintained communication with the designated Russian liaison officer in Deir ez-Zor. They exercised caution, ensuring they only engaged in gunfire after receiving confirmation there were no regular Russian troops involved.
Did the Russians approve of the Battle of Khasham?
While Russian officials insist they weren’t involved in authorizing the Conoco attack, two sources have alleged the participation of a Russian minister. An article by The Washington Post on February 22, 2018, claimed that intercepted communications between the late leader of the Wagner Group, Yevgeny Prigozhin, and senior Syrian and Kremlin officials suggested otherwise.
According to these communications, Prigozhin purportedly “secured permission” from an unnamed Russian minister to proceed with the attack, pending approval from the Syrian government. Additionally, the Ukraine-based anti-Russian publication InformNapalm asserted that the attack had received clearance from Sergej Kim, the chief of Wagner’s operations department and a former Russian naval infantry officer.

Despite these allegations, Russian officials maintained their stance of non-involvement in the attack.
