Greek police have been using masked migrants to forcibly push other migrants back across the country's borders, according to a BBC investigation. The report alleges that these operations, described as involving recruited mercenaries, have been taking place since at least 2020.

The practice described by the BBC involves what are termed "pushbacks" - operations where migrants are forcibly returned across borders without proper asylum procedures. Such actions are considered violations of international law, which requires countries to allow asylum seekers to have their cases heard.

According to the investigation, Greek authorities have recruited migrants to participate in these operations, with the recruited individuals wearing masks during the activities. The BBC characterizes these recruited migrants as mercenaries working on behalf of Greek police forces.

The allegations come amid ongoing scrutiny of Greece's migration policies and border enforcement practices. Greece has faced previous accusations from human rights organizations regarding its treatment of migrants and asylum seekers at its borders.

Greek officials have not immediately responded to the specific allegations outlined in the BBC report. The European Union has previously called on member states to ensure their border practices comply with international law and human rights obligations.
