President Trump used a Tuesday call with Russian President Vladimir Putin to discuss the need for safe zones in Syria, the White House announced.
"President Trump and President Putin agreed that the suffering in Syria has gone on for far too long and that all parties must do all they can to end the violence," the White House said in a statement. "The conversation was a very good one, and included the discussion of safe, or de-escalation, zones to achieve lasting peace for humanitarian and many other reasons."
So-called safe zones in Syria would provide areas where civilians could live under the protection of U.S. and other international forces while the coalition active in Syria continued its actions against the Islamic State. Safe zones would, in theory, shield civilians both from the Islamic State and from the violence of the Assad regime.
Putin and Syrian President Bashar Assad are allies, a dynamic that has complicated U.S. involvement in Syria's conflict.
The White House announced that a Trump administration official would represent the U.S. at ceasefire talks in Kazakhstan later this week.
Trump's conversation with Putin on Tuesday was his first since the U.S. launched a missile strike on a Syrian air base that is also used by Russian forces. Trump ordered the strike in response to Assad's decision to launch a chemical weapons attack in a civilian neighborhood.
Trump and Putin also discussed the "very dangerous situation" in North Korea.
