Erdoğan also spoke with his U.S. counterpart Donald Trump over the phone about the Syrian crisis earlier on Wednesday.
The phone call came after Trump warned Russia on Twitter to brace for U.S. military engagement in Syria following a suspected chemical attack in the city of Douma in Eastern Ghouta on April 8 that killed dozens of people.
Trump also blamed Russia for being partners with “a gas killing animal”, referring to Syria’s Bashar al-Assad.
Trump’s posts on Twitter followed a warning from Moscow that the risk of a direct military clash between Russia and the U.S. in Syria “is higher than before”, with a Russian envoy saying that U.S. missiles flying over the war-ravaged country would be shot down.
