The Turkish president has vowed to unblock what was once considered the main gateway for refugees seeking sanctuary in Europe.
Recep Tayyip Erdogan demanded the US and the EU create a safe zone in northern Syria.
Turkish President Recep Tayyip Erdogan on Thursday threatened to reopen a route for Syrian refugees to reach Europe if it does not receive more support for a a resettlement plan centered on northern Syria.
Erdogan has urged the US to take further action on establishing a so-called safe zone in northeast Syria, where Washington has a military presence in support of a Kurdish-led force fighting the "Islamic State" militant group.
"This either happens or otherwise we will have to open the gates," said Erdogan. "Either you will provide support, or excuse us, but we are not going to carry this weight alone.
We have not been able to get help from the international community, namely the European Union."
