Syria's foreign ministry is warning a US-led military coalition of the "dangers of escalation" and is demanding it stop carrying out air strikes against pro-Damascus forces, state television reports.
On Wednesday it called the coalition illegitimate and said its actions only served to strengthen Islamic State. It did not elaborate or issue a specific threat.
The statement came hours after a military alliance fighting in support of Damascus threatened to hit US positions in Syria - a response to US air strikes on pro-Syrian government forces on Tuesday.
