Moscow will shoot down any U.S. missiles fired at Syria and retaliate against American launch sites, the Russian ambassador to Lebanon has warned. Ambassador Alexander Zasypkin made the comments on Tuesday while speaking on the Hezbollah-affiliated al-Manar TV channel, Reuters reported. President Donald Trump is currently considering military action against Syrian President Bashar al-Assad following Saturday’s suspected chemical attack on the rebel-held town of Douma near the capital city of Damascus. Medical relief groups say the attack killed dozens of civilians.
