U.S. President Donald Trump condemned a deadly Syrian regime attack in northwestern Syria’s Idlib province during a telephone call with Turkish President Recep Tayyip Erdogan, the White House said Friday.

Trump “expressed his condolences and condemned yesterday’s attack that killed Turkish personnel in Syria,” spokesman Judd Deere said in a statement.

“President Trump reaffirmed his support for Turkey’s efforts to de-escalate the situation in northwest Syria and avoid a humanitarian catastrophe,” added Deere. “The two leaders agreed that the Syrian regime, Russia, and the Iranian regime must halt their offensive before more innocent civilians are killed and displaced.”
