SDF general commander Mazloum Abdi called on all sides to “prevent any new tragedies and support de-escalation” Turkish President Tayyip Erdogan had said Ankara planned to rid northern Syria’s Tal Rifaat and Manbij areas of “terrorists” The commander of the US-backed Syrian Democratic Forces (SDF) said on Thursday a new offensive threatened by Turkey in northern Syria would create a humanitarian crisis and undermine a campaign against the Daesh group. SDF general commander Mazloum Abdi called on all sides to “prevent any new tragedies and support de-escalation.” “We are concerned about new Turkish threats which pose high risk on northern Syria. Any offensive will divide Syrians, create a new humanitarian crisis, and displace original inhabitants,” he wrote on Twitter. Turkey has pledged to launch a new military incursion against the Syrian Kurdish YPG militia, the spearhead of the SDF, which controls swathes of the north at the Turkish border. While Turkey views the Kurdish-led forces in Syria as terrorists and a national security threat, the United States views the SDF as a major partner that helped drive Daesh out of vast areas of Syria. President Tayyip Erdogan said on Wednesday Turkey will rid northern Syria’s Tal Rifaat and Manbij areas of terrorists, confirming the targets of the new incursion for the first time and saying it will continue into other regions. Ankara has carried out four operations in northern Syria since 2016, seizing hundreds of kilometers of land and pushing some 30 km deep into the country, mainly targeting the YPG. Washington has expressed concern about any new offensive in northern Syria, saying it would put US troops at risk and undermine regional stability.
