Ukraine sinks Russian border guard ship tied to Kerch Strait attack
Ukraine says it sunk the Russian border guard patrol ship Izumrud near Novorossiysk with a Sargan-3000 sea drone; the vessel took part in the 2018 Kerch Strait attack and reportedly left crew casualties. Kyiv framed the strike as revenge amid a broader campaign that includes attacks on Russian oil infrastructure and a UN update showing rising civilian casualties in June 2026.
