Police in riot gear threw teargas and fired water cannon at Greek islanders as they tried to prevent access to construction sites for new migrant detention centers by setting fires, hurling flares and blockading the gates.
Locals on Lesvos and Chios are worried that the centers, which would replace temporary camps with open access, will leave the islands permanently overcrowded.
Foreign Minister Nikos Dendias in a speech to the annual meeting of the UN Human Rights Council - which this year focused on the protection of children - stressed that Greece has saved the lives of thousands of refugees and migrants and has shouldered a disproportionately large share of the burden of the crisis.
Greek administrative officials and residents of the five Greek Aegean islands accommodating refugees and migrants have staged a protest in Athens against plans to build new camps.
Dozens of protesters from the islands of Lesbos, Chios, Samos Leros and Kos gathered in front of the interior ministry, carrying placards against projects for new refugee camps.
Pairs of Turkish F-16 fighter jets flew numerous times over small islands of the eastern Aegean on Thursday, according to the Hellenic National Defense General Staff (GEETHA).
Two jets flew over Farmakonisi, Arki and Lipsi at a height of 25,000 feet at 1.30 p.m., and were followed by two more that flew over Arki, Lipsi and Agathonisi at 9,000, 10,000 and 20,000 feet, respectively.
