TEHRAN – A warning from the White House to Syrian President Bashar Assad about another possible chemical weapons attack was also aimed at two of President Beshar Assad's key backers, Russia and Iran, the U.S. ambassador to the United Nations said on Tuesday, ABC News reported.

“The goal is at this point not just to send Assad a message, but to send Russia and Iran a message,” Nikki Haley said. “That if this happens again, we are putting you on notice.”
