The US and France have denied Russian claim that Syrian air defence had intercepted at least 71 cruise missiles fired by the US, the UK and French forces early on Saturday.
"None of our aircraft or missiles involved in this operation were successfully engaged by Syrian air defences," Lieutenant-General Kenneth McKenzie, the director of the Joint Staff at the Pentagon, said at a press briefing on Saturday.
He said there were no known civilian casualties, but noted Syria had fired about 40 unguided surface-to-air missiles, most of which didn't launch until after the allied strike was over.
