Background: Russian President Putin has reiterated maximalist war aims of complete Ukrainian capitulation, using Belarus as a cognitive warfare lever, while Russian gains in Kostyantynivka have been limited. On July 3, Putin announced that Russian forces will continue mass strikes targeting Ukraine's military-industrial complex and infrastructure, and will expand the 'security zone' in Sumy and Kharkiv regions in response to Ukrainian strikes on Russian cities. He claimed full capture of Kostiantynivka and the Luhansk region, and advances in Donetsk. A wave of Russian aerial attacks hit Zaporizhzhia and Odesa, including guided aerial bombs on a residential area in Zaporizhzhia injuring eight, and a missile strike on a food storage warehouse in Odesa injuring two. Earlier daytime attacks in Sumy killed four, including one child, and injured 20; in Zaporizhzhia, two were killed and 17 injured, including an 11-year-old child.

On 3 July 2026, Russian President Putin claimed Russian forces had completely captured Kostiantynivka in Donetsk Oblast, a claim timed to US Independence Day. The Institute for the Study of War (ISW) assessed that Russian forces control only about 37% of the city through infiltration, not full capture. Ukrainian President Zelenskyy directly called the claim a lie. Ukraine's Group of Forces 'East' and General Staff officially denied the claim, stating the city remains under Ukrainian control with active combat ongoing. Putin also claimed capture of all Luhansk region and announced plans to expand a 'security zone' into Sumy and Kharkiv regions.

Russia has deployed the new S8000 'Banderol' cruise missile, a hybrid of a kamikaze drone and cruise missile, in large-scale attacks on Ukrainian cities. The missile, produced by sanctioned Russian company Kronshtadt, uses a Chinese Swiwin SW800Pro jet engine and foreign components obtained via sanctions evasion networks. Its high speed makes it difficult for Ukrainian mobile fire teams to intercept, requiring systems like the Gepard. The missile was first documented in late 2024 and has been used in major strikes in 2026, including a record 729-weapon attack.

Ukrainian President Volodymyr Zelenskyy, in a July 4, 2026 message marking the 250th anniversary of the US Declaration of Independence, thanked former President Donald Trump for the 2018 decision to supply Javelin anti-tank missiles and appealed for continued Patriot missile support. The message came days after a major Russian attack on Kyiv killed at least 30 people and drove 52,500 into metro shelters. Zelenskyy linked American historical values to Ukraine's fight for independence, emphasizing the importance of US weapons. Foreign Minister Andrii Sybiha also congratulated the US, thanking Trump for efforts to end the war. The appeal is part of a broader Ukrainian campaign to pressure Moscow to end the conflict.

Ukraine publicly showed its Harpoon anti-ship missile launcher for the first time on 4 July 2026, ending three years of classification, during President Zelenskyy's visit to Odesa. The Harpoon variant is installed in a sea container configuration with four transport-launch canisters. Additionally, a Norwegian-made Naval Strike Missile (NSM) launcher was revealed, though its delivery had never been officially announced; the NSM launcher bears a distinctive Ukrainian paint scheme that does not match any documented source country, leaving its origin unknown. The NSM has a range over 300 km and advanced terminal maneuvering. Ukraine's anti-ship inventory now includes Neptune, Harpoon, RBS 15, and NSM systems, further threatening the Russian Black Sea Fleet.

Background: Russia struck Ukrainian railways roughly 1,200 times in 2025, more than in 2023 and 2024 combined, damaging hundreds of locomotives and cars. Since the full-scale war began, roughly 17,300 railway infrastructure sites and vehicles have been struck, with 7,300 damaged and 9,900 destroyed; 40 railway workers have been killed. Russia has destroyed or damaged over 200 Ukrainian locomotives since the start of 2026, doubling the pace compared to the previous 15 months (209 locomotives hit from January 2025 through March 2026). On 3 July, Russian drones struck railway infrastructure in Dnipropetrovsk Oblast, damaging two locomotives; crews were unharmed due to shelters. Ukrzaliznytsia has deployed over 800 modular mobile shelters at railway junctions and depots since April 2026 to protect crews. CEO Oleksandr Pertsovskyi warned the summer 2026 passenger season will be harder than 2025 due to sustained attacks costing carriages faster than replacement. Ukraine's locomotive fleet averages 46 years old, and a €470 million contract with Alstom for 55 locomotives signed in November 2025 will not deliver the first unit until early 2027, exacerbating the impact.

Ukraine had passed 20 reforms to unlock a $3.39 billion World Bank package. At the Ukraine Recovery Conference in Gdańsk, the country secured over €10 billion in signed documents, with actual disclosed deals approaching $20 billion, including EU disbursements of €7 billion under the Ukraine Support Loan, World Bank financing of $3.39 billion, EBRD risk-sharing facilities with Ukrainian banks, energy investments in wind and solar, defense manufacturing joint ventures, and reconstruction financing. The conference drew nearly 8,000 participants, double the previous year.

Ukraine's Center for Countering Disinformation warned that the Russian FSB, under Director Alexander Bortnikov, is preparing to release falsified WWII documents about the Volhynia tragedy on July 5 to disrupt Ukraine-Poland relations. The warning came as Ukrainian Foreign Minister Andrii Sybiha presented an 'anti-crisis' package to Polish Foreign Minister Radosław Sikorski in Warsaw, proposing consultations, historian convening, and religious outreach to address bilateral tensions over historical memory. The operation is part of a broader Russian strategy to weaken NATO's eastern flank and allied support for Ukraine.
