Ukraine's Security Service (SBU) detained a GRU agent in Zakarpattia Oblast who was building intelligence files on defense-industry engineers and officials for targeted terror attacks. The agent, a local factory employee, compiled addresses of defense enterprises, production volumes, and personal data of workers. The GRU planned to use the intelligence for precision air strikes and assassinations. The agent transmitted information via his father in Kaliningrad. The case follows a pattern of Russian targeting of Ukrainian defense specialists.

Ukraine has intensified a counterlogistics campaign targeting Russian cargo trucks in the 200 km logistical zone behind the front lines, destroying hundreds per day—more than five times the war-long daily average. The campaign uses AI-guided drones, including Swift Beat Hornets, to strike supply lines. Russia may be forced to refurbish tens of thousands of stored Cold War-era trucks, though most are in poor condition. The pivot marks a strategic shift from targeting infantry and deep symbolic targets to disrupting logistics.

Background: Russian forces have conducted coordinated drone attacks on Naftogaz oil and gas infrastructure in Kharkiv and Sumy oblasts, with strikes lasting nearly a full day and causing fires and damage. New development: On Tuesday, Russia escalated its tactics by using a deliberate double-tap strike on a key Naftogaz gas facility in the Kharkiv region: first striking with drones, then launching a missile attack approximately one hour later to maximize damage and endanger responders. Naftogaz CEO Serhii Koretskyi stated that enhanced safety protocols, implemented after a similar attack on May 5 killed employees and rescuers, prevented casualties. The attack was part of a massive overnight Russian aerial assault across Ukraine involving 73 missiles and 656 drones, which killed 13 people and damaged energy infrastructure in multiple regions, including Kyiv, Dnipro, Zaporizhzhia, and Poltava. Ukrainian air defenses shot down or suppressed 642 targets, but impacts from 30 ballistic missiles, 3 cruise missiles, and 33 drones were recorded across 38 locations.

Background: Ukraine previously warned that Russia could announce a mass mobilization after the State Duma elections due to mounting losses and recruitment shortfalls. Now, Russian Duma deputy Andrei Gurulev has publicly predicted a new large-scale mobilization in fall 2025, citing the failure of the winter-spring offensive, heavy losses, and a stalemate at the front. He warned that without solving the problem of Ukrainian drones, mobilization would only increase casualties. The London-based IISS and US-based ISW have also reported on potential Kremlin preparations for renewed mobilization. Ukrainian intelligence confirms ongoing Russian recruitment but says it barely covers losses. Zelensky stated Ukraine has noted Russia's plans to mobilize 100,000 troops and will reinforce its own forces in the Chernihiv-Kyiv sector.

A Russian overnight drone-and-missile barrage on June 1-2 damaged a Chinese Zeekr electric-vehicle dealership in Kyiv's Podil district, forcing it to temporarily suspend operations. The strike occurred during a massive attack on Kyiv Oblast that involved nearly 100 drones and multiple missile types. Separately, Ukraine presented European ambassadors with parts from Russian missiles and drones containing Chinese components, highlighting China's role as a key supplier of dual-use items for Russia's war effort. The incident underscores how Chinese commercial interests in Ukraine are being harmed by Russian weapons that rely on Chinese parts.

Ukraine used its newest automated remote-controlled turrets, including the AI-guided Sky Sentinel system, to defend Kyiv Oblast during Russia's overnight attack on June 2 involving 729 weapons. The turrets, mounted on mobile trailers with heavy machine guns and radar, are part of a layered defense against drone saturation. The 'Clean Sky' project shot down nearly 100 drones. The UK is also delivering over 20 similar Estonian-made turrets as part of a £600 million air-defense package in 2026.

Background: The Russian occupation administration in Crimea imposed strict fuel rationing due to Ukrainian strikes disrupting the land corridor. New development: Ukrainian drone strikes targeting fuel supply routes have caused severe gasoline shortages across Crimea, with 80% of stations unable to sell standard fuel. Moscow-appointed governor Mikhail Razvozhaev called the crisis temporary, but long queues and black market prices persist. Strikes hit rail yards, fuel trucks, and storage sites, including the Marine Oil Terminal in Feodosia, further degrading Crimea's fuel storage capacity. The campaign aims to tighten Ukraine's chokehold on Russian logistics to the peninsula.

Ukrainian President Volodymyr Zelensky announced that military intelligence obtained Russian planning documents outlining efforts to weaken Ukraine's relations with Moldova, South Caucasus countries, and the Middle East and Gulf region. He called for increased European support to counter Russian influence, particularly ahead of elections in Armenia, and stated that Ukraine will propose corresponding measures to partners.

The body of a 76-year-old woman was discovered under the rubble of Novoborovytskyi Lyceum in Chernihiv region, destroyed by Russian shelling on June 1. The woman had taken shelter in the basement during the attack. The lyceum, where 78 children studied remotely, was destroyed by Russian troops who shelled populated areas in Chernihiv region 33 times with strike drones on June 1.

A Russian drone strike destroyed the home of a Ukrainian soldier killed a week earlier during a funeral procession attack in Sumy. The soldier's 5-year-old daughter and wife survived because they had fled the house due to the child's fear. The house was completely burned down after a drone strike shortly after 1 a.m. In Sumy, hits were also recorded on a high-rise building and a private home, with casualties reported.

The General Staff of the Armed Forces of Ukraine reported that Russian forces lost 1,440 troops, 3 tanks, 7 armored vehicles, 75 artillery systems, and one air defense system in the past 24 hours, bringing total estimated Russian combat losses since February 24, 2022, to approximately 1,366,910 personnel. There were 178 combat clashes on the front line over the past day.

Background: Russian forces previously struck an enterprise in the Myrhorod district of Poltava region, damaging technological equipment without casualties. Today, a combined Russian attack on the Poltava region wounded two people and damaged production facilities, residential buildings, vehicles, and farm buildings in the Lubny district. Police and security services are documenting the attack as a war crime.

Russian President Vladimir Putin signed a decree requiring most foreign applicants for Russian citizenship to submit a criminal record certificate issued by their country of citizenship or identity document issuer, valid no more than three months before application. The requirement does not apply to Ukrainian citizens eligible for simplified procedures, including residents of occupied territories. The move tightens immigration controls while maintaining fast-track citizenship programs in occupied Ukraine, which Western governments condemn as a violation of international law. The decree follows broader efforts to tighten immigration controls, including legislation preventing foreigners with outstanding criminal convictions from obtaining citizenship or residency. Russia continues fast-track citizenship programs in occupied Ukraine, having issued approximately 3.5 million passports to Ukrainians in occupied territories, a practice condemned by Ukrainian authorities and Western governments as a violation of international law.

A Ukrainian court sentenced Russian Colonel General Aleksandr Lapin to life imprisonment in absentia for planning and directing the 2022 invasion of Ukraine, including the failed attempt to capture Kyiv. Lapin is currently in Russia.

Ukraine's National Anti-Corruption Bureau (NABU) and Specialized Anti-Corruption Prosecutor's Office (SAPO) uncovered a scheme involving the alleged embezzlement of nearly Hr.170 million ($4 million) from state-owned Energoatom during construction of the Tashlyk Pumped Storage Hydroelectric Power Plant in Mykolaiv region. Two suspects were named: the beneficial owner of contracting companies and a former department head at Atomproektengineering. Investigators allege that despite delays and bankruptcy, Energoatom officials continued signing additional agreements, including an inflated purchase of an automated control system. The case is part of broader anti-corruption efforts in Ukraine's energy sector.
