Turkish Leader Threatens Action in Libya, Syria Dorian Jones Turkish President Recep Tayyip Erdogan is threatening action in both Libya and Syria as rhetoric ramps up in the face of looming regional setbacks and growing frustrations with Moscow. Erdogan, addressing parliament Tuesday, issued a stark warning to Damascus not to violate the latest brokered cease-fire in Syrian rebel-controlled Idlib province. "We hope the cease-fire in Syria's Idlib is lasting. Turkey is determined to prevent (Syrian leader Bashar al-) Assad regime attacks in violation of the truce," said Erdogan to cheers from his parliamentary deputies. "Everyone should see and accept this is no joke.Turkey will absolutely do whatever it says it will do," he added. The Turkish president called on Damascus to allow 400,000 Syrians that had fled to Turkey's border to be allowed to return to their homes in Idlib. Turkey is currently hosting over 3.5 million Syrian refugees amid growing public discontent blamed in part for a series of humiliating election defeats for Erdogan's ruling AKP. Analysts say Erdogan is determined to prevent another exodus of Syrian refugees entering Turkey. Turkish military forces are deployed in Idlib as part of a previous agreement struck with Moscow to enforce a de-escalation zone. While Ankara backs Syrian rebels, the two countries are increasingly cooperating in Syria as part of a broader rapprochement. .
