A top Russian lawmaker warned on Tuesday that Moscow could respond with military force to a potential U.S. strike on Syria in the wake of a deadly chemical weapon attack.

Vladimir Shamanov, the chairman of the defense affairs committee in the State Duma, said in televised remarks that Russia would consider "all political, diplomatic and military measures" against the U.S. in the event of a strike in Syria.

"The politics of double standards have hit rock bottom," Shamanov said, according to the Russian state-run TASS news agency. "And here the United Russia party conscientiously states that all political, diplomatic and military measures if necessary will be taken. No illegal action will remain unanswered."

Shamanov's comments came a day after President Trump Donald John TrumpBubba Wallace to be driver of Michael Jordan, Denny Hamlin NASCAR team Graham: GOP will confirm Trump's Supreme Court nominee before the election Southwest Airlines, unions call for six-month extension of government aid MORE said that he would consider a possible retaliatory move against Syria, as well as its allies of Russia and Iran, for the chemical weapons attack in a suburb of Damascus over the weekend, which killed at least 40.

Trump said that Monday that he would make a decision on a response in the next 48 hours.

Shamanov denied on Tuesday that the Syrian government used chemical weapons and asserted that a U.S. strike in Syria would amount to a violation of the country's sovereignty.

"We won’t let the Americans hammer nails on someone else’s anvil," he said, according to TASS.

Trump ordered a missile strike on a Syrian air base in April 2016 in response to another deadly chemical weapons attack. That retaliatory strike did only modest damage.

The U.S. gave Russia a heads up before the 2016 missile strike, and no Russian assets were targeted.
