Russia said its forces had struck a railway station at Ukraine's Izmail port on the Danube River and two tugboats near the city of Mykolaiv, according to TASS news agency, citing Russia's Defense Ministry.
The Defense Ministry said the railway station in Izmail was used for unloading, storage, and transport of military cargo and fuel for Ukraine's armed forces. It also said Russian forces sank two tugboats off the coast of Mykolaiv, which it claimed were escorting ships carrying weapons to Ukrainian ports.
These developments followed a previous day's Russian attack that damaged port infrastructure and caused power outages in Izmail, a key export hub near the Romanian border.
On the Ukrainian side, Russian officials said a Ukrainian drone attack sparked a fire at Ust-Luga, a major oil export port on the Baltic Sea in the Leningrad region. Governor Alexander Drozdenko said the fire was contained, with no casualties, and that more than 50 drones were shot down overnight in the area around St. Petersburg.
Ukraine has for months been striking Russian oil refineries, ports, and energy facilities to raise the economic cost of Moscow's war. More than a dozen major Russian refineries have been hit, contributing to domestic fuel shortages.
Also overnight, a drone fragment damaged the wall of a warehouse belonging to the online retailer Wildberries in the northwest of Moscow, according to the governor of the Tver region. No casualties were reported. Wildberries facilities have been hit more than 20 times in the past month.
Due to drone activity, Russia's Federal Air Transport Agency (Rosaviatsia) temporarily restricted flights at all airports in the Moscow region to ensure safety, according to TASS.
Drone activity also prompted Baltic states to bolster their defenses. Latvia's armed forces said its fighters shot down a drone that entered its airspace. Meanwhile, Finland temporarily restricted maritime traffic in parts of the Baltic Sea as a precaution against potential drone incidents.
