On May 17, Russian President Vladimir Putin called for foreign forces to withdraw from Syria at a press conference with Syrian President Bashar al Assad. Russia's envoy to Syria clarified Putin's comments the next day, saying they applied to Turkish, U.S., Iranian, and Hezbollah forces. The Russian statement seemed to expose a disagreement between Moscow and Tehran. For years, Iran and Russia have cooperated in their efforts to bolster the Syrian regime against rebels and extremist groups. "No one can force Iran to do anything," Iranian Foreign Ministry Spokesman Bahram Ghassemi said in response. The following are remarks from Syrian, Iranian and Russian officials.

We proceed from the assumption that in view of the significant victories and success achieved by the Syrian Army in its fight against terrorism, and the start of a more active phrase of the political process, foreign armed forces will be withdrawing from the territory of the Syrian Arab Republic.
