Syrian state TV initially said the United States was suspected of carrying out a missile attack on the T-4 airfield near Homs, after harsh words by Trump over the reported chemical attack on Saturday in the town of Douma which killed dozens of people.

The United States denied attacking the Syrian base, and France also said its forces had not carried it out.

The Russian military, whose forces are supporting Syrian President Bashar al-Assad, said two Israeli F-15 war planes had carried out the strikes on the Syrian T-4 air base, the Interfax news agency reported.
