US slams Israel strike on Syria, calls it 'unnecessary escalation'

US' envoy for Syria Tom Barrack criticised Israel's airstrikes on Syria's Abu al-Duhur Airbase, calling it an "unnecessary escalation that doesn't advance regional stability". "[Syria's] government has neither adopted predatory posture nor maintained proxy forces. It has repeatedly indicated preference for de-escalation," Barrack added. He further said US encourages "diplomatic cadence".
