Ukraine Conflict Monitor

ACLED’s Ukraine Conflict Monitor provides near real-time information on the war, including an interactive map of the latest data from the start of the invasion onward, a curated data file, and weekly situation updates.

The Monitor is designed to help researchers, policymakers, media, and the wider public track key conflict developments in Ukraine over the course of the war. It is updated every Wednesday, with data covering events from the previous week. ACLED data reflect the best available information at the time of release, and are regularly updated as new or better information becomes available.

Due to  the methodological limitations of event-based data collection, in addition to the broader challenges around fatality reporting in fast-moving conflict contexts like Ukraine, fatality estimates in the ACLED dataset pertain specifically to those fatalities reported in connection with distinct events that meet ACLED’s catchment and minimum threshold for inclusion (i.e. date, location, and actor information). This means that aggregate tallies provided by sources such as hospitals and government agencies, for example, which cannot be broken down and connected to individual conflict incidents, are not included in the ACLED dataset. ACLED fatality numbers are conservative event-based estimates, and the full death toll in such contexts is likely higher than the number of reported fatalities currently attributed to the type of distinct incidents that can be captured in the dataset. For these reasons, the Monitor will not be providing regular fatality estimate updates at this time.1Tracking fatalities is one of the most difficult aspects of conflict data collection in general, as fatality counts are frequently the most biased, inconsistent, and poorly documented components of conflict reporting, and this is especially true of active conflict environments impacted by high levels of mis/disinformation and severe access constraints. ACLED defaults to conservative estimates based on the best available information at the time of coding in line with our specific event-based methodology and review process. ACLED estimates are restricted to fatalities reported during individual events, meaning that these estimates may be particularly conservative in comparison with sources that do not use an event-based methodology. When and where possible, ACLED researchers seek out information to triangulate the numbers from any report, but we do not independently verify fatalities. ACLED is also a ‘living dataset’, so all fatality figures are revised and corrected — upward or downward — if new or better information becomes available (which, in some conflict contexts, can be months or years after an event has taken place). These figures should therefore be understood as indicative estimates rather than definitive fatality counts (for more on ACLED’s approach to coding fatalities, see FAQs: ACLED Fatality Methodology). ACLED additionally only captures fatalities that are directly caused by political violence; indirect conflict-related fatalities caused by disease or starvation, for example, are not included in these estimates. Other sources may come to different figures due to differing methodologies and catchments.

20 – 26 May 2023

Fighting between Ukrainian and Russian forces continued in the areas of Bakhmut and Avdiivka in the Donetsk region and along the Kreminna-Svatove-Kupiansk line in the Luhansk and Kharkiv regions. On 20 May, Russia’s Wagner Group claimed to have captured what remained of Bakhmut after a year of almost daily shelling, airstrikes, and clashes, with Ukrainian forces admitting that only a small number of Ukrainian troops remain in the city.2New York Times, ‘With Bakhmut in Ruins, Ukraine Shifts Focus to City’s Outskirts,’ 22 May 2023 Meanwhile, Ukrainian forces reportedly continued to advance around Bakhmut3Riley Bailey et al, ‘Russian Offensive Campaign Assessment, May 26, 2023,’ 26 May 2023 and launched long-range strikes on Russian forces in Berdiansk in the Zaporizhia region and Mariupol in the Donetsk region. The Wagner Group also exchanged 106 captured Ukrainian soldiers for an unspecified number of Russian prisoners of war on 25 May. 

Russian shelling, missiles, and airstrikes reportedly killed over a dozen civilians in the Dnipropetrovsk, Donetsk, Kherson, and Luhansk regions last week. On 26 May, a Russian missile hit a hospital in Dnipro in the Dnipropetrovsk region, killing four civilians and wounding 30. Russian forces also continued to launch drone strikes across the country, damaging residential buildings and other civilian infrastructure in Kyiv city and the western Chernivtsi region.
