US President Donald Trump on Tuesday said he would remove all sanctions against Syria, saying they had served an important function, but it was now time for Syria to move forward.
"I will be ordering the cessation of sanctions against Syria in order to give them a chance at greatness," Trump told an investment forum in Riyadh.
"It's their time to shine. We're taking them all off," Trump said, "Good luck Syria, show us something very special," he added.
