The Russian military said on Monday that two Israeli F-15 warplanes had carried out strikes on a Syrian air base on Sunday, the Interfax news agency reported.
Interfax cited the Russian Defense Ministry as saying the Israeli warplanes had carried out the strikes from Lebanese airspace, and that Syrian air defense systems had shot down five of eight missiles fired.
Asked about the Russian statement, an Israeli military spokesman said he had no immediate comment.
Syrian state TV said on Monday the United States was suspected of striking an air base hours after U.S. President Donald Trump warned of a "big price to pay" as aid groups said dozens of people were killed by poison gas in a rebel-held town.
