Germany, Hungary, and other European countries have called for asylum seekers who initially landed in Greece to be returned to the Mediterranean country.
Late last month, Greek Prime Minister Alexis Tsipras said a deal was reached to return refugees and migrants from Germany to Greece and Spain.
However, Kyriakos Giaglis, Greece's country director for the Danish Refugee Council, explained that previous attempts to return asylum seekers to Greece were "never really" implemented.
"Here in Greece, all of the sites are overcrowded, and we have very bad situations in most of the sites,” he said.
“We don't know where they would be returned.”
