REUTERS: Americans will be expelled from Iraq and Syria, Iran's Supreme Leader Ayatollah Ali Khamenei said on Sunday (May 17), renewing Iran's demand for US troops to be withdrawn from the Middle East.

Iran almost got into a full-blown conflict with the United States when a US drone strike killed top Iranian military commander Qassem Soleimani in Baghdad on Jan 3, prompting Tehran to retaliate with a missile barrage against a US base in Iraq days later.
