WASHINGTON (AP) — The U.S. ambassador to the United Nations says President Donald Trump told her if the Syrian regime uses poisonous gas again, “the United States is locked and loaded” to strike again.

Nikki Haley relayed the message from Trump at an emergency meeting of the U.N. Security Council on Saturday. She says, “When our president draws a red line, our president enforces the red line.”

Haley says the message from the U.S., U.K. and French airstrikes earlier Saturday that “crippled Syria’s chemical weapons program” was “crystal clear.”

She says, “The United States of America will not allow the Assad regime to continue using chemical weapons.”

Haley accused Russia of defending Syrian President Bashar Assad and failing to ensure that Syria’s chemical weapons were destroyed as the Assad regime had pledged in 2013.
