Greece treats migrant flows as national security issue as hundreds reach its islands

Greek soldiers repair the fence after riots at the closed Kastanies border crossing in northeastern Greece, where refugees and migrants gathered on the borderline between Greece and Turkey from the Turkish side, near the Evros River, in an attempt to cross into Greece, on March 2, 2020. Greece on Sunday decided to increase the level of deterrence at its borders to the maximum, as the country is facing a forthcoming increased refugee and migrant influx recently.
