WASHINGTON, May 17 (Xinhua) -- U.S. President Donald Trump on Sunday warned that "the clock is ticking" for Iran, threatening again that the country would be left with nothing if its leadership failed to act quickly.

"For Iran, the clock is ticking, and they better get moving, FAST, or there won't be anything left of them. TIME IS OF THE ESSENCE!" Trump wrote on Truth Social.
