[Note: The Ukrainian General Staff's 0800 SITREP appears to cover battlefield activity from 0800 on the previous day to 0800 on the current day, the 1600 SITREP appears to cover battlefield activity from 0000 to 1600, and the 2200 SITREP appears to cover battlefield activity from 0000 to 2200. Any reports of Russian ground activity in the Ukrainian General Staff's April 20, 2200 SITREP are by default an accusation of Russia's 30-hour unilateral Easter truce that started at 1800 Moscow time on April 19. ISW is unable to assess whether Russian attacks reported in the Ukrainian General Staff's April 21, 0800 SITREP occurred after the end of the truce.]
Russian President Vladimir Putin rejected Ukrainian President Volodymyr Zelensky's April 20 proposal for a temporary moratorium on long-range strikes against civilian infrastructure, declined Zelensky's offer to extend Putin's own 30-hour Easter truce, and attempted to justify recent Russian strikes against civilian targets in Ukraine. Zelensky stated on April 20 that Ukraine and Russia achieved a long-range strikes ceasefire between April 19 and 20 and during the day on April 20 and proposed a temporary ceasefire on long-range missile and drone strikes against civilian infrastructure for a minimum of 30 days, with the opportunity to extend the ceasefire beyond 30 days.[1] Putin announced the end of the Easter truce on April 21 and rejected Zelensky's proposed temporary moratorium on long-range strikes against civilian infrastructure while speaking to journalists, stating that Russia would need to "sort out" the proposed civilian infrastructure strikes moratorium.[2] Putin attempted to soften his rejection of Zelensky's ceasefire proposal by claiming that Russia and other unspecified actors need to study strikes against civilian targets where military personnel are operating and "make appropriate decisions." Putin did not suggest the possibility of creating independent monitoring mechanisms to determine the legitimacy of such strikes, and Russian officials have previously expressed disinterest in Western-led monitoring mechanisms as a condition of future ceasefires in Ukraine.[3] Putin also attempted to justify Russia's recent missile strikes against Ukrainian civilian infrastructure and to obfuscate his ongoing rejection of US and Ukrainian ceasefire proposals. Putin acknowledged that Russian forces recently struck civilian infrastructure in Sumy City — likely referring to the April 13 Russian missile strike against Sumy City — but suggested that the reported presence of Ukrainian military personnel in Sumy City constituted a legitimate military target.[4] Putin claimed that Russian forces also targeted Ukrainian military personnel during a recent Russian strike against Odesa City.
Putin reiterated his rejection of the full ceasefire that Zelensky and the US have offered. Zelensky reiterated on April 20 Ukraine's readiness to agree to a full and unconditional ceasefire for a minimum of 30 days.[5] Putin rejected the full ceasefire proposal on April 21, claiming that Ukraine was attempting to "seize the initiative and talk about expan[ding]" the ceasefire, and alleging that Russia would need to "carefully evaluate everything."[6] Ukraine and the United States initially proposed a full ceasefire on March 13, and Putin and other Russian officials have repeatedly rejected the proposal over the past five weeks.[7] The US Department of State told Reuters on April 20 that the United States would welcome the extension of the Easter truce, however.[8] US President Donald Trump expressed hope on April 20 that Russia and Ukraine would make a deal this week, possibly referring to a general ceasefire agreement that would precede future peace negotiations.[9] Kremlin Spokesperson Dmitry Peskov appeared to respond to Trump's statement by stating that the Kremlin is not ready to discuss a time frame to end the war.[10] Putin's continued rejection of the US-Ukrainian March 2025 proposed general ceasefire and the Kremlin's refusal to commit to any time frame to end the war highlight Putin's disinterest in ending the war via peace negotiations in the near term.[11] Putin's continued rejection of US and Ukrainian ceasefire proposals runs counter to Trump's stated approach of first establishing a ceasefire and then negotiating a broader peace agreement and to Trump's goal of achieving a lasting peace in Ukraine.
Russian state media amplified Kherson Oblast occupation head Vladimir Saldo's calls for additional territorial concessions from Ukraine in areas to which Russia has not yet laid formal claim. Saldo stated on April 21 to Kremlin newswire TASS that the "return" of the west (right) bank of the Dnipro River is "fundamentally important" and an "absolute priority" for Russia.[12] Saldo claimed that Ukrainian forces will continue efforts to use the east (left) bank of the river as a "lever of pressure" against Russia and that the presence of Ukrainian forces on the west bank hinders the resumption of shipping along the river. Saldo concluded that "the segment of the [Dnipro River] that passes through Kherson, Zaporizhia, and Dnipropetrovsk oblasts must be completely under [Russian] control" so as to guarantee the development of infrastructure "associated with the river." Russian forces only currently occupy positions on the east bank of the Dnipro River in Kherson and Zaporizhia oblasts, yet Russian President Vladimir Putin has consistently demanded since June 2024 that Ukraine cede all of Zaporizhia and Kherson oblasts to Russia.[13] Saldo appears to be calling for additional Russian territorial claims along the river in central Dnipropetrovsk Oblast — an oblast tha...
