Turkey's Coast Guard Command rescued 3,763 asylum-seekers that were pushed back by Greece between January and May, according to coast guard data.
The teams saved 169 asylum-seekers in January, 524 in February, 825 in March, 1,620 in April and 625 in May.
The Turkish coast guard rescued 12,655 people from the seas in 2020, 11,493 of whom were irregular migrants.
Turkey and human rights groups have repeatedly condemned Greece's illegal practice of pushing back asylum-seekers, saying it violates humanitarian values and international law by endangering the lives of vulnerable migrants, including women and children, yet similar incidents keep occurring.
Numerous reports by journalists, researchers and witnesses have cataloged the way in which migrants and asylum-seekers have been forced back across the border to Turkey or left stranded in the Aegean Sea without aid by the Greek coast guard, despite the conservative government's denials in Athens.
Human Rights Watch (HRW) in March stated that reports from 2020 recorded multiple incidents in which Greek coast guard personnel, sometimes accompanied by armed masked men, intercepted, attacked, disabled and pushed back boats carrying migrants.
Pushbacks are considered contrary to international refugee protection agreements that say people should not be expelled or returned to a country where their life or safety might be in danger due to their race, religion, nationality or membership of a social or political group.
