THESSALONIKI, Greece (AP) — Greek Prime Minister Kyriakos Mitsotakis has criticized Turkish President Recep Tayyip Erdogan for a statement he made last week about opening the gates for Syrian refugees to massively migrate into Europe.

Mitsotakis said at a news conference in the northern Greek city of Thessaloniki on Sunday that Erdogan can't "threaten" Greece and the European Union by trying to wrest more money to deal with mass migration, adding that the bloc has already provided Turkey with 6 billion euros in aid.

Mitsotakis also criticized EU countries for not doing their part to accept refugees, especially unaccompanied children, saying that if they couldn't show solidarity with fellow EU members, they should leave the Schengen area of free peoples' movement.
