The US Department of State (DoS) announced on May 1 that it has determined that Russian forces are violating the Chemical Weapons Convention (CWC), to which Russia is a signatory. The US DoS stated that it made a determination under the Chemical and Biological Weapons Control and Warfare Elimination Act of 1991 (CBW Act) that Russian forces have used chloropicrin and riot control agents (RCAs) against Ukrainian forces in Ukraine in violation of the CWC.[28] Chloropicrin is a pesticide and lung damaging agent, and Ukrainian officials have previously reported that Russian forces are increasingly equipping grenades with chloropicrin.[29] Russian forces have reportedly extensively used chlorobenzylidenemalononitrile (CS) gas, a type of RCA, in grenades dropped from drones on Ukrainian positions throughout the frontline.[30] The US DoS noted that Russian forces likely use chemical weapons in an effort to dislodge Ukrainian forces from fortified positions and achieve tactical gains.[31] Kremlin Spokesperson Dmitri Peskov denied the US DoS determination and claimed on May 2 that Russia is abiding by its obligations to the CWC.[32] ISW previously observed the Russian 810th Naval Infantry Brigade acknowledge in a now-deleted post that elements of the brigade deliberately used K-51 grenades with CS gas on Ukrainian positions near Krynky in east (left) bank Kherson Oblast in December 2023.[33] The US DoS also announced sanctions against the Russian Ministry of Defense's (MoD) Radiological, Chemical, and Biological (RCB) Defense Forces; the stated-owned Scientific Research Institute of Applied Acoustics; and the MoD’s 48th Central Scientific and Research Institute as well as four Russian companies for their involvement in the development and use of chemical weapons.[34]
Russian President Vladimir Putin met with Tula Oblast Governor and known Wagner Group-affiliate Alexei Dyumin on May 2, further indicating that Putin may be seeking to reduce Russian Defense Minister Sergei Shoigu’s power by balancing him with rivals. Dyumin notably briefed Putin about Tula Oblast’s contributions to Russia's full-scale invasion of Ukraine at the presidential estate in Novo-Ogaryovo, Moscow Oblast.[39] Dyumin focused on three topics: support and housing for participants of Russian military personnel fighting in Ukraine, improvements to the Russian defense industrial base (DIB) and improving the medical system in Tula Oblast. Dyumin claimed that the Tula Oblast administration is cooperating with the Russian MoD to fully equip Russian military units with necessary materiel identified by the local commanders. Dyumin also boasted that Tula Oblast opened one of the first training centers for drone operators in cooperation with the Russian MoD to support the Russian MoD and other security agencies’ interests. Dyumin emphasized the Tula Oblast administration's commitment to producing weapons and supporting Russia's industrial base (DIB). Dyumin welcomed Russian Deputy Prime Minister and Minister of Trade and Industry Denis Manturov’s proposal for the federal government to assist with the construction of additional DIB enterprises and bragged about Russia's increasing DIB production capabilities. Dyumin’s brief appeared to be an attempt to win Putin's favor following Dyumin’s notable fall from Putin's grace during Wagner Group Yevgeny Prigozhin’s mutiny in late June 2023.[40] Dyumin repeatedly sided with Prigozhin throughout 2022 and 2023 reportedly in an attempt to facilitate firings within the Russian MoD and possibly hoping to replace Russian Defense Minister Sergei Shoigu himself.[41]
Putin likely deliberately publicized his meeting with Dyumin following the high-profile arrest of Russian Deputy Defense Minister Timur Ivanov on April 24 and before the presidential inauguration on May 7, possibly to punish the Shoigu-led MoD for failing to accomplish the Kremlin's military goals. The Putin-Dyumin meeting generated a significant amount of discourse within the Russian information space, with numerous milbloggers and political commentators pointing out that the meeting occurred between Ivanov’s arrest and the expected government reshuffle following the inauguration.[42] Russian insider sources speculated that the Kremlin may appoint Dyumin to a new role involving the Russian DIB, such as deputy chairman of the Russian Military Industrial Commission.[43] These speculations may be the result of Dyumin’s hyperfocus on DIB and mention of Manturov during his meeting with Putin. Russian insider sources also interpreted Shoigu’s May 1 statement that Russia needs to increase the volume and quality of weapons and military equipment to ”maintain the required pace of the offensive” during the meeting at the Joint Headquarters of the ”Special Military Operation” on the night of May 1 as a direct attack on certain Russian political figures.[44] (Prigozhin similarly justified Wagner Group's slow and bloody advance in Bakhmut, Donetsk Oblast in winter 2023 with claims of ammunition shortages that he colorfully blamed on Shoigu.) One political commentator claimed that Shoigu is trying to shift the blame for his military and DIB failures onto Manturov and the CEO of Russian state-owned defense conglomerate Rostec, Sergei Chemezov. Another Russian insider source similarly claimed on May 1 that Shoigu heavily criticized Manturov, Rostec, and Deputy Chairman of the Russian Security Council Dmitry Medvedev in response to Ivanov’s arrest.[45] Shoigu reportedly had a particularly close relationship with Ivanov and that Ivanov’s arrest alongside the sudden reemergence to prominence of Dyumin may indicate that the Kremlin is dissatisfied with Shoigu’s performance.[46] One Russian source, however, assessed that Shoigu‘s dismissal is unlikely in 2024.[47]

Russian Defense Minister Sergei Shoigu issued a notably candid assessment of recent Russian advances in Ukraine and refrained from sweeping claims about the success of the Russian war effort, possibly in an attempt to temper domestic expectations about Russia's near future successes in Ukraine ahead of the summer 2024 Russian offensive operation. Shoigu claimed during a conference call with Russian military leadership that Russian forces have seized 547 square kilometers of territory in Ukraine since January 1, 2024.[33] ISW has observed evidence confirming that Russian forces have seized approximately 516 square kilometers in 2024 as of April 29, and Shoigu’s claim is notably more realistic than previous claims that surpassed ISW’s assessed Russian advances by roughly 100 square kilometers.[34] Shoigu also reiterated the Russian Ministry of Defense's (MoD) previous claims that Russian forces have seized Novobakhmutivka, Semenivka, and Berdychi and ongoing Kremlin information operations aimed at overestimating Ukrainian manpower and equipment losses.[35]
Shoigu claimed that Russian forces are continuing to break into Ukrainian strongholds along the entire frontline and are forcing Ukrainian forces to retreat from their positions in unspecified areas. Shoigu previously used a similar conference call in December 2023 to downplay Russian operations in Ukraine as an “active defense,” likely in an effort to temper expectations about Russia's forces’ months-long operation to seize Avdiivka.[36] Shoigu may hope to similarly temper domestic expectations about Russian forces anticipated Summer 2024 offensive operation, particularly since Russian forces will be facing better-equipped Ukrainian forces than the Russian military command likely previously expected.
