The UN Security Council will meet behind closed doors Thursday to address the Turkish military operation against Kurdish fighters in northeast Syria.

The discussion by the 15-member Security Council was requested by the five European members, Britain, France, Germany, Belgium and Poland, diplomats said.

On Wednesday, France, Britain and Germany were prepared to issue a statement strongly condemning Turkey’s operation, French European Affairs Minister Amélie de Montchalin said.

The three countries “are finalizing a joint statement that will be extremely clear on the fact that we condemn very strongly and firmly what has been reported,” Montchalin told Parliament’s Foreign Affairs Committee in response to a question about Turkey’s moves.

She added that a separate European Union statement from the bloc’s 28 states had yet to be agreed on because some countries had not signed it, according to Reuters. One source said Hungary had blocked the statement.

European Commission President Jean-Claude Juncker urged Turkey to “halt its military operation.”

US Sen. Lindsey Graham (R-SC) and Rep. Liz Cheney (R-Wyo.), usually reliable allies of President Trump, assailed him Wednesday after Turkey began its offensive.

“Pray for our Kurdish allies who have been shamelessly abandoned by the Trump Administration. This move ensures the reemergence of ISIS,” Graham said in a tweet. Referring to Turkish President Recep Tayyip Erdogan, Graham vowed to lead congressional efforts “to make Erdogan pay a heavy price.”

He added: “I urge President Trump to change course while there is still time by going back to the safe zone concept that was working.”

Cheney called the situation “sickening” and said it was “impossible to understand why @realDonaldTrump is leaving America’s allies to be slaughtered and enabling the return of ISIS.”
