The EU and Turkey will hold a "special meeting" in early March to push forward an aid-for-cooperation deal to curb migrant flows to Europe, European Council President Donald Tusk said Friday.

"We agreed that our joint action plan with Turkey remains a priority and we must do all we can to succeed. This is why we have the intention to organise a special meeting with Turkey in the beginning of March," Tusk told a press conference after the first day of an EU summit.
