Turkey summoned the Greek ambassador to Ankara to the foreign ministry to protest about what it said was Greece providing opportunities for terrorist groups to conduct activities, state-owned Anadolu news agency reported on Friday.
Ambassador Christodoulos Lazaris was also summoned after Greece allowed a protest near the Turkish embassy in Athens by the militant Kurdistan Workers Party (PKK), which Turkey and the European Union regard as a terrorist group, Anadolu said.
President Tayyip Erdogan said this week Turkey was halting talks with Greece, partly over a row with its prime minister and what Ankara calls airspace violations, in the latest setback for the neighbours' long-troubled relationship.
