US-brokered 9-11 May ceasefire and 1,000-prisoner swap announced

On 8 May 2026 President Trump announced in a Truth Social post that Russia and Ukraine had agreed to a ceasefire covering 9, 10 and 11 May 2026 that would “include a suspension of all kinetic activity, and also a swap of 1,000 prisoners from each Country,” adding: “Hopefully, it is the beginning of the end of a very long, deadly, and hard-fought War.”¹ The Kremlin readout was delivered by Aide to the President Yuri Ushakov; the Office of the President of Ukraine, President Volodymyr Zelenskyy, confirmed Ukrainian acceptance in his nightly video address.²³ The 9 May start coincides with Russia’s Victory Day (Den’ Pobedy, День Победы), commemorating the Soviet victory in the Great Patriotic War (Великая Отечественная война, 1941-1945). Unlike the war’s prior pauses, the 9-11 May arrangement is an agreed, US-brokered bilateral ceasefire. It follows the collapse of the same week’s dueling unilateral declarations: Russia announced a unilateral 8-9 May Victory Day truce on 4 May — coupled with a threat of a “massive missile strike” on Kyiv if Victory Day festivities were disrupted — and Ukraine declared its own ceasefire from midnight on 6 May with no end date; Ukrainian authorities reported 1,820 Russian violations by 10 a.m. on 6 May.⁴ Russia’s earlier unilateral pauses — the 19-20 April 2025 Easter ceasefire and the 8-10 May 2025 Victory Day ceasefire — were each followed by resumption of strikes after expiry.⁵ The framework builds on the 28 December 2025 Trump-Zelenskyy Mar-a-Lago meeting and the 20-point plan Zelenskyy then described as “approximately 90 percent” agreed.⁶

1. A 72-hour agreed ceasefire creates a verifiable compliance test: monitoring relies on the two parties’ own reporting through the Kremlin and the Office of the President of Ukraine, plus the US mediation channel; the United Arab Emirates, Saudi Arabia and Türkiye have mediated the war’s large prisoner exchanges, and Qatar has mediated the return of forcibly transferred Ukrainian children since 2023.⁷ European governments and NATO welcomed the agreed pause while noting that prior unilateral declarations had been broken within hours.

2. Prisoner exchanges of 1,000 each side draw from custody pools held by the Russian Ministry of Defence (with GUR / FSB liaison on the Russian side) and the Coordination Headquarters for the Treatment of Prisoners of War on the Ukrainian side; the swap procedure follows the framework refined across exchanges since 2022, with the 24 January 2024 Belgorod IL-76 incident the largest disruption to date.⁸ Geneva Convention III governs prisoner-of-war treatment in the international armed conflict; Russia revoked its declaration under Article 90 of Additional Protocol I recognising the competence of the International Humanitarian Fact-Finding Commission in October 2019, notified to the Swiss depositary on 23 October 2019.⁹¹⁰

3. Either party’s resumption of offensive operations at hour 73 returns the operational picture to pre-ceasefire status; prior Russian-declared pauses were followed by resumption within hours of expiry, and observers will measure compliance against (i) the absence of cross-border strikes, (ii) the absence of front-line offensive movement, and (iii) the completion of the 1,000-for-1,000 swap by hour 72.¹¹
