A TOP human rights official urged Greek authorities yesterday to address claims of negligence over a 2023 boat disaster that killed hundreds of migrants off the coast of southern Greece.

Michael O’Flaherty, the Council of Europe’s human rights commissioner, cited recent findings by Greece’s Ombudsman that maintained coast guard officers failed to prevent one of the Mediterranean’s deadliest migrant shipwrecks.

An estimated 500-750 people were aboard the overcrowded Adriana when it sank while travelling from Libya to Italy in waters off Pylos in southern Greece in June 2023.
