DAMASCUS, April 14 (Reuters) - At least six loud explosions were heard in Damascus on Saturday and smoke was seen rising over the Syrian capital, a Reuters witness said.
Syrian state TV said the army's air defences were confronting an attack by the United States, France and Britain.
A second witness said the Barzah district of Damascus had been hit in the strikes. Barzah is the location of a major Syrian scientific research centre.
