Ukraine strikes Kronstadt naval base and Leningrad arsenals in 1,000km drone attack timed to St Petersburg forum

Ukrainian drones on Saturday struck Kronstadt — the main base of Russia's Baltic Fleet — and military arsenals in the Leningrad region in what Zelensky described as a 1,000km-range mission; Leningrad governor Alexander Drozdenko reported more than 140 drones shot down, a fire at a military facility, and resident evacuations, while St Petersburg governor Alexander Beglov issued the city's first stay-at-home order since February 2022. Zelensky simultaneously struck a Krasnodar region oil depot 500km away as part of Ukraine's 'long-range sanctions,' and declared the attacks a just response to Russian strikes. The assault fell on the final day of Russia's St Petersburg International Economic Forum, a day after Putin, speaking at the same forum, refused Zelensky's request for direct peace talks.

Ukraine calls for international humanitarian corridor to evacuate starving civilians from Russian-occupied Oleshky

Ukraine is urging the international community to establish a humanitarian corridor to evacuate up to 2,000 civilians, including nearly 50 children, from the Russian-occupied city of Oleshky, where famine has taken hold since March. The city, flooded after the 2023 Kakhovka dam destruction and heavily mined, has been cut off from food deliveries since mid-January, with only one truck arriving on May 4. Kyiv says a truce date from Moscow is needed to begin the evacuation, which would require supervision by the United Nations or the Red Cross.

The unit is destroying Russian equipment and disrupting logistics along the route, complicating fuel and military deliveries to the peninsula. The operation adds pressure on Russia's constrained supply lines, including the Kerch Bridge and the corridor through occupied Donetsk Oblast.

Hungary agrees to lift veto on Ukraine EU accession talks but defers final block to referendum

Hungarian Prime Minister Péter Magyar announced on Wednesday a comprehensive agreement with Ukraine on minority rights for ethnic Hungarians in Zakarpattia, clearing the way for Budapest to support opening the first negotiating cluster in Ukraine's EU accession talks once the measures are legislated. However, Magyar pledged that if Ukraine completes all 33 accession chapters within 10 to 15 years, Hungary will hold a binding national referendum on final admission, effectively relocating the veto to the end of the process. The deal also unlocks €16.4 billion in frozen EU funds for Hungary.

Ukraine builds 822 km of anti-drone road tunnels for frontline logistics in 2026

Background: Ukraine previously installed over 1,170 km of anti-drone protection on frontline logistics routes by April 2025, with construction pace doubling to 8.5 km per day. As of May 2026, Ukraine has built 822 km of anti-drone protection since the start of the year, including 211 km added in May alone. The State Special Transport Service also restored 38 km of previously damaged protected segments and rebuilt 115.5 km of standard frontline roads. The protection uses overhead netting tunnels, wire-mesh canopies, and reinforced barriers to intercept Russian FPV drones, enabling safer supply deliveries, casualty evacuations, and personnel rotations. Russia has responded by restricting civilian transport on occupied highways, including the R-280 'Novorossiya' route and the R-150 Belgorod-Mariupol highway, due to Ukrainian drone threats.

Russia concentrates over 140,000 troops on three southern front sectors, Syrskyi reports

Ukraine's Commander-in-Chief Oleksandr Syrskyi reported that Russia has concentrated more than 140,000 troops across three hot sectors of the southern front: over 71,000 in the Oleksandrivka sector, with similar numbers in the Huliaipole and Orikhiv sectors. During a working trip to frontline units, Syrskyi discussed strengthening positions, supported commanders' initiatives for active operations, and ordered additional technical equipment and ammunition. He also met with Major Robert Brovdi, commander of the Unmanned Systems Forces, to discuss the development and use of unmanned systems, emphasizing the preservation of soldiers' lives as the top priority. Subsequently, Ukrainian military spokesperson Viktor Tregubov reported that the highest Russian activity is currently on the Lyman front, where Russian forces are attempting to advance toward the Sloviansk–Kramatorsk agglomeration but are being stopped by well-prepared Ukrainian defenses. The situation near Kupiansk is more complicated, with Russian forces concentrating drone units to strike Ukrainian logistics on the eastern bank of the Oskil River. Russian attempts to break through toward the town on the right bank via Holubivka failed. In Vovchansk, combat has intensified but remains stable. In the Velykyi Burluk area, Russian forces have shifted to defense after recent failures, now controlling only one settlement. Over the past day, 269 combat engagements were recorded.
