Paris (AFP) — French President Emmanuel Macron made clear to Donald Trump “the absolute necessity to prevent a re-emergence” of the Islamic State (IS) jihadist group, after the US pulled its troops out of northern Syria.

Macron warned, in a telephone call on Monday evening, that the troop pullout and Turkey’s subsequent offensive against the Kurds in the region increased the threat of an IS resurgence, the presidential palace said.

The French leader also held talks with Turkish President Recep Tayyip Erdogan and Iraqi counterpart President Barham Saleh, the presidency said.

Paris and other European capitals are concerned that the IS members held by the Kurdish authorities could escape and take advantage of the chaos in the region to regroup.

According to Macron’s office, the conversation between the French president and Erdogan “underlined the deep divergence of views on the expected consequences of the Turkish offensive in the north east of Syria.”

According to an account of the conversation provided by the Turkish authorities, Erdogan “explained” to Macron “the objectives of the operation” and “drew attention to the threat posed by the terrorist groups of Islamic State and YPG for Turkey’s security and Syria’s territorial integrity.”

The YPG Kurdish People’s Protection Units (YPG) militia had US support in its efforts to overcome IS and now feels isolated as it comes under attack from Turkey.

The conversation between Macron and Iraqi president Saleh focussed “on the humanitarian and security risks of the current situation,” as well as “on the measures to be taken within the framework of the international coalition against the Islamic State.”

Macron told Saleh he hoped to see “a strengthening of French-Iraqi cooperation” in this context.
