Trump sent 'strong message' to Iran, Russia and Syria with missile strikes: White House spokesperson

Trump showed that he will enforce his "red line," Sarah Sanders said.

Sanders continued, “They went out to destroy critical chemical weapons infrastructure in Syria and they did exactly that. And they also sent a strong message to Syria, to Russia, to Iran that when this president has a red line, he will enforce it,” she said referring to the administration's "red line" against use of chemical weapons.

"We have to stop the spread and the use of mass chemical weapons," she said.

"What kind of a nation wants to be associated with the mass murder of innocent men, women, and children?” the president said.

Russia and Syria have both denied any use of chemical weapons by the Assad government in the country's civil war.

But a report released by the White House on Saturday, hours after the missile attack on Syria, said, “The United States assesses with confidence that the Syrian regime used chemical weapons in the eastern Damascus suburb of [Douma] on April 7, 2018, killing dozens of men, women, and children, and severely injuring hundreds more.”
