Turkish Foreign Minister Cavusoglu said that Turkey was re-evaluating the refugee deal with Europe
In an interview with broadcaster A Haber, Mr Cavusoglu said the migrant deal and visa liberalisation were a package, and added it was Turkey's right to re-evaluate or suspend these if one element was not fulfilled.
He said: "We are not applying the re-admission agreement at the moment, and we are evaluating the refugee deal."
Mr Cavusoglu also said Turkey currently had no issues with Russia and would strengthen cooperation on a ceasefire and political solution in Syria, after a chemical attack blamed on Syrian government forces killed scores in rebel-held Idlib province, prompting the United States to launch a missile strike on a Syrian air base.

Earlier this week, President Erdogan claimed Europe "is collapsing" and "will pay" for the way it has treated Turkey.
