## Recent evidence

- [confirms] French Navy seizes sanctioned Russian-linked tanker 450 miles from Réunion in the Indian Ocean (2026-10-13): The French Navy seized the sanctioned, Russian-linked tanker DF Peak (formerly Kaliningrad), which was sailing under a false Benin flag, 450 miles from Réunion in the Indian Ocean.
