Trump warns Russia to 'get ready' for U.S. airstrike in Syria

President Trump in an April 11 tweet warned Russia to “get ready” for a U.S. airstrike in Syria aimed at the Assad regime. 

"Russia vows to shoot down any and all missiles fired at Syria. Get ready Russia, because they will be coming, nice and new and 'smart!'" he wrote. "You shouldn’t be partners with a Gas Killing Animal who kills his people and enjoys it!"

Meanwhile, Russia has threatened to attack the "sources" of any missiles fired into Syria. 

"If there is a strike by the Americans, then we refer to the statements of President Putin and the chief of staff that the missiles will be downed and even the sources from which the missiles were fired," Russian Ambassador to Lebanon Alexander Zasypkin told Hezbollah's al-Manar TV.
