Damage to the Kakhovka Hydroelectric Power Plant (KHPP) dam in the early hours of June 6 caused massive flooding of the Dnipro River delta, river wetlands, estuaries, and shoreline settlements in Kherson Oblast. Russian and Ukrainian sources began reporting loud noises resembling explosions emanating from the KHPP (across the Dnipro River in the Nova Kakhovka area about 55km northeast of Kherson City) between 0200 and 0230 local time on June 6, followed by reports of rushing water and an overall increase in the water level of the Dnipro. Ukraine’s Kherson Oblast Administration announced the evacuation of several raions (districts) of the west (right) bank of Kherson Oblast as of 0730 local time and reported that the Tyahinka, Odradokamianka, Beryslav, Ivanivka, Mykilske, Tokarivka, Ponyativka, Bilozerka, and Ostriv areas had been partially or completely flooded. Russian Kherson Oblast occupation officials announced the evacuation of the Nova Kakhovka, Hola Prystan, and Oleshky raions. Ukrainian officials noted that over 80 settlements are within the flood zone in Kherson Oblast. General Director of Ukraine’s hydroelectric power plant regulator Ukrhydroenergo Ihor Syrota said that water is draining from the Kakhovka Reservoir at a rate of 15-20cm an hour, which Syrota stated means that the reservoir will be entirely dry in the next four days. A researcher at the Ukrainian Department of Water Bioresources at the Kherson Oblast Agrarian and Economic University, Yevhen Korzhov, noted that the rate of water discharge from the dam may lead to flooding as far downstream as Kizomys, about 120km southwest from the KHPP. A Russian milblogger claimed that the water level in Nova Kakhovka, immediately adjacent to the KHPP, reached as high as 11m. Various Russian sources additionally highlighted footage showing that several east (left) bank settlements, including Oleshky, Korsunka, and Dnipryany, are entirely or nearly entirely underwater.

Russian and Ukrainian officials are signaling the start of the Ukrainian counteroffensive. ISW offers no assessment of these signals at this time. The Russian Ministry of Defense (MoD) claimed on June 5 that Ukrainian forces conducted a “large-scale offensive” across five sectors of the frontline in southwestern Donetsk Oblast on June 4. The Russian MoD claimed that Russian forces repelled all Ukrainian attacks and assigned Chief of the Russian General Staff Army General Valery Gerasimov to oversee the southwestern Donetsk frontline. Ukrainian Deputy Defense Minister Hanna Malyar noted on June 5 that Ukrainian forces are “transferring to offensive actions” in some unspecified areas of the front. Malyar added that Russian sources are actively spreading information about the Ukrainian counteroffensive to deflect attention from Russian losses in the Bakhmut direction. The Russian MoD’s claims that Russian forces immediately repelled Ukrainian counteroffensives are consistent with previous false Russian claims made during past counteroffensives. Ukrainian forces are likely making limited gains despite Russian denials. ISW will not attempt to assess at this time whether or not these gains are part of broader counter-offensive operations. ISW observed an increase in combat activity in different sectors of the frontline but will not speculate about the intent, weight, or focus of Ukrainian counteroffensives operations. A successful counteroffensive operation may take days, weeks, or even months before its outcome becomes fully clear, during which time Russian sources may falsely claim to have defeated it.

Elements of the all-Russian pro-Ukrainian Russian Volunteer Corps (RDK) and Freedom of Russia Legion (LSR) conducted another limited raid into Belgorod Oblast on June 4 and are reportedly continuing to operate in a Russian border settlement. Geolocated footage published on June 4 shows LSR and RDK personnel advancing towards Novaya Tavolzhanka (3.5km from the Ukrainian border). Belgorod Oblast Governor Vyacheslav Gladkov confirmed that there was fighting within Novaya Tavolzhanka, although the Russian Ministry of Defense (MoD) claimed that units of the Western Military District and the Russian Border Guard Service struck a Ukrainian sabotage and reconnaissance group near the settlement, forcing them to withdraw. Russian milbloggers claimed that a sabotage and reconnaissance group of 20 personnel entered Novaya Tavolzhanka without armored vehicles. Wall Street Journal Chief Foreign Affairs Correspondent Yarsoslav Trofimov reported that the pro-Ukrainian Russian fighters remain in Novaya Tavolzhanka as of 1700 (Moscow Standard Time).

Ukrainian officials continue to signal that Ukrainian forces are prepared to start counteroffensive operations. Ukrainian President Volodymyr Zelensky stated in a June 3 interview with the Wall Street Journal that Ukraine is ready to launch a counteroffensive. Zelensky stated that Ukraine “would like to have certain things, but … can’t wait for months” to start counteroffensive operations. Ukrainian Deputy Defense Minister Hanna Malyar stated on June 3 that “military plans love silence” and that she will “discuss something else” in the meantime, likely acknowledging that Ukrainian officials have started to more strictly enforce a regime of informational silence about operations in preparation for upcoming counteroffensives. Ukrainian Minister of Internal Affairs Ihor Klymenko stated on June 3 that Ukraine has formed all nine brigades of the “Offensive Guard” and that these formations are ready to take part in hostilities at Zelensky’s and Ukrainian Commander in Chief General Valeriy Zaluzhnyi’s orders.

The Russian Ministry of Defense (MoD) continues to respond disproportionately to limited raids into Russian territory, likely to project confidence and competence in the MoD’s ability to respond to perceived threats. The Russian MoD issued a second update about the June 1 Shebekino, Belgorod Oblast border raid, largely fixating on the timeliness and scope of the Russian response to the raid. The MoD claimed that additional Russian Western Military District (WMD) elements reinforced the border area within an hour of the start of the raid and conducted heavy air, artillery, and flamethrower strikes against the raiding units and their reserves. The MoD claimed that over 135 people and 35 vehicles in total conducted the raids and that various Russian defensive efforts - including small arms fire and mines - repelled the raids. The MoD later celebrated the commander of an unspecified motorized rifle battalion, Lieutenant Colonel Alexander Nikitin, for leading the defensive effort, likely to preempt attempts to attribute the “victory” achieved by Belgorod border defense on Russian Colonel General Alexander Lapin as the information space did during the May 23 raid. The Russian MoD’s fixation on portraying Russian forces and the Russian military command as capable defenders of Russia likely reflects internal and broader information space anxiety over the coming Ukrainian counteroffensive as well as any reverberating informational impacts from any failures to defend against Ukrainian counterattacks.

Russian forces conducted another series of missile strikes on Ukraine overnight on May 31 to June 1 and during the day on June 1. The Ukrainian General Staff reported that Russian forces launched 10 Iskander ballistic missiles targeting Kyiv City from Bryansk Oblast, which borders Ukraine, in the morning on June 1, and that Ukrainian air defense destroyed all 10 missiles. The Ukrainian General Staff also reported that Russian forces launched two S-300 missiles targeting critical infrastructure in Kharkiv City during the day on June 1. Ukrainian Air Force Spokesperson Colonel Yuriy Ihnat stated that Ukraine cannot strike launch points of Russian Iskander missiles in Russia as Ukraine is under obligations not to strike Russian territory with Western-provided weapons. ISW has previously assessed that Russian forces began a new limited air campaign in recent months to degrade Ukrainian counteroffensive capabilities, but that the Russian prioritization of Kyiv is likely further limiting the campaign’s ability to meaningfully constrain potential Ukrainian counteroffensive actions.

The Russian military command has likely ordered Chechen Republic Head Ramzan Kadyrov’s forces to begin offensive operations in Ukraine following the withdrawal of Wagner Group forces from Bakhmut. Kadyrov claimed on May 31 that Chechen forces received a new order and assumed responsibility over the Donetsk Oblast frontline. Kadyrov claimed that Chechen units need to start “active combat activities” and “liberate a series of settlements.” Kadyrov added that Chechen “Akhmat” Special Forces (Spetsnaz) and the “Sever-Akhmat” Special Purpose Regiment transferred to the Marinka direction southwest of Donetsk City. The Russian Ministry of Defense (MoD) also claimed that assault detachments of the 5th Separate Motorized Rifle Brigade of the 1st Army Corps and Akhmat Spetsnaz conducted offensive operations in the Marinka direction. Kadyrov noted that the Russian military command ordered Russian, Rosgvardia (Russian National Guard), and Chechen Akhmat forces to begin offensive actions along the frontline in Zaporizhia and Kherson oblasts as well. Kadyrov claimed that these units have already begun tactical preparations for these offensive actions and claimed that “Akhmat” units’ offensive operations began before Ukrainian forces launched a counteroffensive. ISW has observed no indications of Chechen offensive operations in Zaporizhia or Kherson as of this writing.

Russia claimed that Ukraine conducted a series of drone strikes against Moscow on May 30 as Russia again targeted Ukraine with Iranian-made Shahed drones. The Russian Ministry of Defense (MoD) accused Ukraine of attacking Moscow with eight drones on the morning of May 30, and claimed that Russian forces shot down five of the drones and suppressed three drones with electronic warfare systems. Russian propagandist Vladimir Solovyev, however, claimed that Ukraine launched 32 drones of which some targeted the prestigious neighborhood of Rublyovka in Moscow Oblast. A Russian independent outlet claimed that the drone strikes predominantly targeted areas near Russian President Vladimir Putin’s residence in Novo-Ogaryovo and other elite neighborhoods in Moscow Oblast. Moscow Mayor Sergei Sobyanin stated that several buildings in Moscow suffered minor damage, and Russian sources amplified footage of a minor explosion in the Novaya Moskva neighborhood. A Russian milblogger claimed that drones flying over Moscow resembled Ukrainian attack drones. Geolocated footage shows Russian forces shooting down drones identified as Ukrainian by OSINT accounts in several different areas of Moscow and Moscow Oblast. Ukrainian presidential aide Mykhailo Podolyak denied that Ukraine was directly involved in the drone strike but forecasted that there could be an increase in such attacks in the future.

Russian forces conducted another series of strikes against Ukraine with cruise missiles and Iranian-made drones overnight on May 28 to 29 and during the day on May 29. The Ukrainian General Staff reported that Russian forces launched 40 Kh-101/Kh-555 air-based cruise missiles and 38 Shahed-131/136 drones on the night of May 28 to 29 and 11 Iskander-M/K missiles during the day on May 29. The Ukrainian General Staff reported that Ukrainian air defenses destroyed in all 36 Kh-101/Kh-555 cruise missiles, 30 Shahed drones, and all 11 Iskander missiles. Ukrainian officials reported that Ukrainian forces intercepted all 11 Iskander missiles, and 40 cruise missiles and Shahed drones that targeted Kyiv City and Kyiv Oblast. Ukrainian sources reported that Ukrainian forces also intercepted missiles and drones near the cities of Lviv, Mykolaiv, and Odesa, and that Russian forces struck port infrastructure in Odesa City and a military infrastructure facility in Khmelnytskyi Oblast. Russian forces launched a relatively higher number of missiles than in recent series of strikes following the largest Russian series of Shahed strikes since the start of the full-scale invasion of Ukraine on May 28. ISW previously assessed that Russian forces began a new limited air campaign in recent months to degrade Ukrainian counteroffensive capabilities, but that the Russian prioritization of targeting Kyiv is likely further limiting the campaign’s ability to meaningfully constrain potential Ukrainian counteroffensive actions.

Russian forces conducted the largest Shahed drone strike against Ukraine since the start of the war overnight on May 27-28. The Ukrainian General Staff reported that Russian forces launched 59 Shahed-131/136 drones, of which Ukrainian forces shot down 58. Ukrainian Air Force Spokesperson Colonel Yuriy Ihnat characterized this strike as the largest drone strike since the start of the war and stated that Russian forces chiefly targeted Kyiv. Zhytomyr Oblast Head Vitaliy Bunechko reported that Russian drones struck an unspecified infrastructure facility in the oblast. The Russian allocation of aerial munitions to targeting Kyiv rather than prioritizing infrastructure or military facilities continues to constrain this limited Russian air campaign’s ability to meaningfully degrade Ukrainian offensive capabilities for the upcoming counteroffensive, as ISW has previously assessed.
