Drone attacks damage two Russian ports; Crimea reports power outages and casualties

Impact verdict

Low impact. The event combines reported physical damage to port infrastructure, vessel strikes involving fuel tankers, and disruption to power infrastructure in occupied Crimea, creating direct war-risk and marine exposure pathways in the Black Sea theatre. However, available reporting does not identify the two ports, quantify port or vessel losses, or confirm casualty numbers, and Western insured interest in occupied-territory energy and infrastructure assets is likely limited. On current evidence, London Market aggregation appears constrained but could rise if port identities, vessel losses, or internationally insured interests are confirmed.
