Russia 'ghost ships' actively hunted by Ukraine in deadly cat and mouse battles at sea

Open-source intelligence analysts have compiled a report tracking these so-called "ghost ships" on journeys from the Russian military base at Novorossiysk to the country's Tartus naval base in Syria. As on land, Russian supply lines at sea are vulnerable to attack from Ukrainian forces. Kyiv is said to have already come close to sinking one of the 'ghost ships' in what OSINT researcher Jack Crawford described as a "near miss".
