Josip Borel said: The European Union will intensify after the cease-fire agreement concluded by Moscow and Ankara to help civilians affected by the conflict.
"A ceasefire is a good thing, let us see how it goes, but it is a precondition for increased humanitarian assistance to the population in Idlib," he told reporters before chairing a meeting of European Union foreign ministers in the Croatian capital, Zagreb.
In response to a question about the possibility of imposing a no-fly zone in Idlib, he explained, "We must focus our efforts on the humanitarian side."
Borrell noted that the European Union governments will consider Friday allocating more money to migrants in Turkey, stressing that the bloc will not accept the use of refugees as a bargaining tool by Ankara.
The European official said that Turkey bears "a great burden, we must understand this. But at the same time we cannot accept the use of refugees as a source of pressure", referring to Ankara's decision to open its borders with Greece.
