The targets appeared to steer well clear of any Russian personnel or equipment in Syria, where Moscow launched a military intervention in support of Assad in 2015.
The Russian military claimed Syrian air defense systems had intercepted 71 Western missiles, though the Pentagon flatly dismissed the claim and said all missiles hit their targets.
– Too little, too late? –
In central Damascus, dozens of Syrians arrived on bicycles, on foot and in cars spray painted with the red, white, and black colors of the Syrian flag, blaring patriotic tunes.
Despite the strikes, the Organisation for the Prohibition of Chemical Weapons said it was still pursuing its investigation into the Douma attack.
Thousands of rebels and civilians have since been bussed out of the town under a Russian-brokered deal. Syrian internal security forces entered Douma on Saturday and later said the town had been fully retaken.
Jaish al-Islam, the group that held Douma, said it only abandoned the town because of the chemical attack.
Ahmad, a 25-year-old mechanic who had been displaced from Douma, told AFP the Western strikes were nevertheless too little, too late.
“Assad won’t collapse. They’ll bomb for a day or two and then the regime will take it out on us,” he said.
