In June 2023, EU ombudsman Emily O'Reilly launched a probe into the European Border and Coast Guard Agency (Frontex) The probe was launched over the Adriana boat tragedy in which more than 600 people lost their lives off the coast of Greece. The Mediterranean Sea continues to be the most lethal route for migrants with at least 3,129 deaths and disappearances registered last year.
Frontex has long been accused of human rights violations, covering up or turning a blind eye to illegal pushbacks.
