“The actions of the US coalition do not comply with legal norms. Beyond all doubt, it is aggression,” Klintsevich, the first deputy chairman of the Federation Council’s Committee for Defense and Security, told Interfax on Thursday.
“The Americans have never acted so openly before in Syria – this is unprecedented.”
On Wednesday, the US-led coalition said it carried out several “defensive” airstrikes on Syrian forces in retaliation for what they described as an “unprovoked” attack on the so-called Syrian Democratic Forces (SDF) and foreign military “advisers.”
More than 100 fighters aligned with Syrian President Bashar Assad were killed in the strike, Reuters reported, citing an unnamed US official.
The retaliatory attack was carried out after Syrian “pro-regime forces initiated an unprovoked attack against well-established Syrian Democratic Forces headquarters,” the coalition claimed.
Although there is no legal justification for the US presence in Syria, which has endured a six-year conflict and partial occupation by Islamic State, a Pentagon spokesman said in December that US forces would stay “as long as we need to, to support our partners and prevent the return of terrorist groups.” The Pentagon earlier admitted that it has 1,720 troops in Syria, more than three times as many as it had previously acknowledged.
In May of last year, the US forces in Syria bombed a militia group fighting alongside the Syrian government forces in southern Syria. The coalition said in a statement that the Syrian forces “posed a threat” to the US and partner troops at Tanf military base near the Syria-Iraq-Jordan border.
The airstrike was condemned by Moscow. Russian Foreign Minister Sergey Lavrov said it represented yet another violation of Syria’s sovereignty by the US.
“The American command explained the strike on pro-government Syrian forces, saying that these forces represented a threat to opposition which cooperates with the US-led coalition,” Lavrov said in May. “Whatever the reason for the US command to make this decision, this strike is illegitimate and unlawful. It’s yet another harsh violation of Syria’s sovereignty.”
In early June, the US-led coalition struck Syrian pro-government forces near its training base of At-Tanf, and shot down an armed drone outside its deconfliction zone. “U.S. conducted strikes against two technical vehicles that we were assessed to be posing a threat to Coalition forces at At-Tanf garrison,” Operation Inherent Resolve spokesman Colonel Ryan Dillon tweeted.
