US-led coalition’s downing of Syrian plane ‘act of aggression’ & ‘support for terrorists’, says Russian official on Monday, reported Russia Today news agency.

US-backed Syrian Democratic Forces (SDF) rebels vowed to “retaliate” in case of Syrian army’s attack their positions in Raqqa. The statement comes following the US-led coalition’s downing of a Syrian army jet in the area.

On June 18, the Syrian army said that the US-led coalition had brought down its aircraft in southern Raqqa countryside when it was fulfilling its mission against Daesh.

Later, the coalition confirmed the information saying that it shot down the Syrian government forces’ Su-22 aircraft as it had allegedly been bombing in an area where US-backed rebel forces, the Syrian Democratic Forces (SDF), were stationed, south of Tabqa in the Raqqa province. The US-led coalition called its attack on the Syrian army’s jet “collective self-defense,” adding that it contacted the Russian military to de-escalate the situation after the incident.

Russian Foreign Minister Sergei Lavrov has urged Washington to respect Syria’s sovereignty and refrain from unilateral moves after the US downed a Syrian bomber in Raqqah.

“We call on the United State and all others who have their forces or advisers on the ground to ensure the coordination in our work,” Lavrov said, adding “zones of de-escalation are one of the possible options to jointly move forward.”

US-led coalition downed Syrian army plane in southern Raqqa countryside – army statemen reported.

Pro regime outlets claiming that international coalition has shot down a regime plane over Raqqa after it targeted YPG areas.

“This attack comes at a time when the Syrian Arab army and its allies are advancing in the fight against ISIS terrorists who are being defeated in the Syrian desert in more ways than one,” the statement read.

The statement added that although such attacks seek to undermine the Syrian armed forces’ struggle against terrorism, they will not be deterred in fighting for stability and security in the Syrian Arab Republic.

This is not the first time that the US-led intervention in Syria has led to standoffs and violence against pro-government forces. In September 2016, a coalition airstrike on Deir ez-Zor killed over 60 Syrian soldiers while in April 2017, US President Donald Trump ordered a Tomahawk missile strike on the Shayrat airbase, ostensibly in retaliation for the use of chemical weapons by the Syria government, though no concrete evidence of this has emerged.
