The day was dominated by the assassination of a Russian Navy officer in Sevastopol, reportedly a Ukrainian submarine commander who had defected. State-aligned outlets (TASS, RIA, NTV) and commercial sources (Lenta, Interfax) covered the bombing and the detention of a female suspect, while independent media (Meduza, Moscow Times) provided details on the victim's background. Concurrently, Ukrainian drone attacks on Russian infrastructure continued: a Gazprom refinery in Salavat was hit, causing a fire and halting operations, and a logistics complex near Ufa was targeted. Putin's first visit to the Kuril Islands drew a formal protest from Japan, with state media emphasizing his 'genetic code of a winner' remarks. In the afternoon, Russia and Ukraine exchanged civilian prisoners in Belarus, and Lavrov reiterated Russia's right to choose targets in response to Western 'piracy'.
