Following reports of the use of refugees in so-called pushbacks, the EU Commission has called on Greece to end "violent and illegal" refusals of asylum seekers.
"Protecting the EU's external borders from illegal entry is an obligation," said EU Interior Commissioner Ylva Johansson on Twitter on Thursday after talks with several Greek government officials.
"Forcible and illegal deportations of migrants must stop now."
Johansson reminded that the disbursement of EU funds for migration and border management is linked to the “correct application of EU fundamental rights”.
Several European media reported on Tuesday that the Greek police were using refugees for pushbacks at the EU's external border.
Several refugees were forced to force people to return to Turkey, reports the “Spiegel” and the ARD, among others.
In return, they were promised residence permits.
According to the report, the police want to protect their own officers - the pushbacks are considered very dangerous.
According to European law, Greece must allow asylum seekers who reach Greek territory to seek asylum, but has ignored this law for years.
In April, the Council of Europe denounced a significant increase in unlawful refusals of asylum seekers in European countries.
