Cypriot President Nicos Anastasiades said Tuesday that his country will not accept the European Union's migration deal with Turkey without concessions from Ankara in the dispute over the Mediterranean island.

"Cyprus does not intend to consent to the opening of any new chapters if Turkey does not fulfil its obligations," Anastasiades said after talks with EU chief Donald Tusk, who said "the key question of legality" still needed to be sorted out for the deal.
