RFERL:
After Russia said that foreign troops should leave Syria when the war ends, Tehran responded by saying no one can force Iran to do anything.
Russian President Vladimir Putin said on May 17 after a meeting with his Syrian counterpart, Bashar al-Assad: "We presume that, in connection with the significant victories and success of the Syrian Army in the fight against terrorism, with the onset of a more active part, with the onset of the political process in its more active phase, foreign armed forces will be withdrawn from the territory of the Syrian Arab Republic."
A day later, Alexander Lavrentiev, Putin’s envoy for Syria, left no doubt that Putin’s comment was aimed at the United States, Turkey, Iran, and Hezbollah.
“As long as it is necessary, the risk of terrorism in Syria exists, and the Syrian government wants Iran to continue its support, we will remain in Syria,” Bahram Ghasemi, spokesman for Iran’s Foreign Ministry, said on May 21.
