WASHINGTON          -          US President Donald Trump thanked President Recep Tayyip Erdoğan by phone for preventing a “humanitarian catastrophe” in northwestern Syria’s Idlib province, the White House said Sunday. “Trump expressed concern [yesterday] over the violence in Idlib, Syria and thanked Erdoğan for Turkey’s efforts to prevent a humanitarian catastrophe,” deputy press secretary Judd Deere said in a statement.“President Trump conveyed the United States’ desire to see an end to Russia’s support for the [Assad] regime’s atrocities and for a political resolution to the Syrian conflict,” he added. The two leaders also discussed the need to eliminate foreign interference in Libya, Deere said. “President Trump also reiterated that continued foreign interference in Libya would only serve to worsen the situation,” he added. Turkish troops are in Idlib as part of an anti-terror and peace mission. In September 2018, Turkey and Russia agreed to turn Idlib into a de-escalation zone in which acts of aggression are expressly prohibited. But more than 1,800 civilians have been killed in attacks by the regime and Russian forces since, flouting a 2018 ceasefire and a new one that began Jan. 12. Libya’s legitimate government has been under attack by Haftar since last April, claiming the lives of more than 1,000 people.
