A US-backed force battling Daesh in eastern Syria accused regime and Russian warplanes on Saturday of bombing its fighters.
A top aide to President Bashar Assad also said on Friday the Syrian government would fight any force, including US-backed forces also battling Daesh militants, in its drive to recapture the whole of the country.
“Whether it’s the Syrian Democratic Forces, or Daesh, or any illegitimate foreign force in the country... we will fight and work against them so our land is freed completely from any aggressor,” Bouthaina Shaaban said in an interview with Hezbollah’s Al Manar TV.
It marked the first time the Syrian Democratic Forces (SDF), an alliance of Arab and Kurdish fighters, have said they have been hit by Russia.
The SDF and Russian-backed Syrian regime forces are conducting parallel but separate offensives against Daesh in the strategic and oil-rich eastern province of Deir Ezzor.
Regime troops are waging an assault for the provincial capital, Deir Ezzor city, while SDF fighters battle the militants further east across the Euphrates River.
“At 3:30 a.m. on Sept. 16, 2017, our forces east of the Euphrates River were targeted by Russian and Syrian regime warplanes in the Al-Sinaaiya area,” the SDF said. It said six of its fighters were wounded.
Al-Sinaaiya is an industrial area northeast of the city of Deir Ezzor, about 7 km from the east bank of the Euphrates.
“At a time when the SDF’s brave forces are scoring great victories against IS (Daesh) in Raqqa and Deir Ezzor... some parties are trying to create obstacles to our progress,” the statement said.
The SDF’s assaults against Daesh in Deir Ezzor and in Raqqa further up the Euphrates Valley are both backed by the US-led coalition, while regime troops are getting air cover from Russia. SDF fighters say they not coordinating their Deir Ezzor operations with the government or Russia. But the coalition says there is a de-confliction line to prevent the two offensives from clashing.
The line agreed between Russia, the regime, the SDF and the coalition runs from Raqqa province southeast along the Euphrates River to Deir Ezzor.
The skies over Syria have become increasingly congested as the six-year conflict has dragged on, with warplanes from the coalition, the Syrian government and Russia all carrying out airstrikes.
Confrontations between the warplanes have been rare, but in June a US fighter jet shot down a Syrian warplane accused of bombing SDF units in the country’s north.
Syria’s crisis erupted with protests demanding the ouster of President Bashar Assad in 2011, but it has since morphed into a complex, multi-front war that has killed 330,000 people and displaced millions.
Daesh, which in 2014 overran swathes of territory across Syria, is seeing its zones of control dwindle even as it claims responsibility for bloody attacks abroad.
It once held most of Deir Ezzor province and its capital, encircling around 100,000 civilians that still lived in government-controlled neighborhoods there.
But Russian-backed troops breached the Daesh sieges on the city earlier this month and are now working to shut off the militants’ remaining escape routes.
Daesh has also been pushed out of two-thirds of its former bastion Raqqa by the SDF.
And in desert territory just across the border in Iraq, security forces backed by tribal fighters are maneuvering into position to launch an offensive against one of Daesh’s last remaining bastions.
After driving Daesh out of Nineveh Province earlier this year, the Iraqi government set its eyes on Hawija, north of Baghdad, as well as the towns of Al-Qaim, Rawa and Anna in the western desert.
