Damascus' allies have condemned US President Donald Trump for ordering air attacks in Syria "on targets associated with chemical weapons capabilities" in collaboration with the UK and France, Al Jazeera reports.
Russia's ambassador to the US warned that there would be consequences for the attacks early on Saturday.
"A pre-designed scenario is being implemented," Russian Ambassador Anatoly Antonov said on Twitter.
"The barbaric aggression ... will not affect in any way the determination and insistence of the Syrian people and their heroic armed forces," state news agency SANA cited an official source in the Syrian foreign ministry as saying.
