It will most likely take many years to identify all those civilians who died during Russia’s assault on Mariupol – and we may never have a full account. Many were killed during attacks or as a result of injuries for which they were unable to get treatment. Others died in the weeks and months following Russia’s siege of the city because they did not have access to clean water or medicine.

During the first half of March 2022, Mariupol residents buried the bodies of their loved ones, neighbors, and strangers in shallow makeshift graves in their backyards, the courtyards of apartment blocks, and in grassy areas where children used to play. Given the ongoing fighting and bombardment of the city, many were unable to bring bodies to hospitals, morgues, or cemeteries, and city officials only managed to promptly collect a fraction of the bodies.

The remains of some victims were likely mixed in with the rubble of damaged and destroyed buildings, never to be identified before demolition and reconstruction efforts began. Still others may have been buried outside of Mariupol. Some of those buried in makeshift graves were later transferred to official cemeteries in and around the city.

To better grasp how many people died, we analyzed satellite imagery, photographs, and videos of five of Mariupol’s cemeteries. We estimate that at least 10,284 people died and were buried in these five cemeteries during the first year of the conflict, though likely many more died. We estimate that around 2,250 people would have died naturally in Mariupol during that time, meaning the city had at least 8,034 excess deaths above a peacetime rate.

It is not clear how many of the people buried in these cemeteries were civilians – including those who died as a result of unlawful attacks – and how many were combatants.

With the city still under Russian occupation, many witnesses to abuses committed during or after the fighting who remain in Mariupol cannot speak about their experiences without risking retaliation. Physical evidence of crimes committed by Russian and affiliated forces has most likely disappeared or been destroyed. As a consequence, the full extent to which civilians died, were injured, or are still missing as a result of Russian forces’ battle for control of Mariupol against Ukrainian forces is unknown.

Grave Types

Single Graves & Trench-Style Graves in Cemeteries

Single graves

These are graves that appear to have been dug individually. We counted these graves one by one, using very-high resolution satellite imagery.

Trench-style graves

These are rows that stretch for between 10 and 70 meters with small wooden plaques placed on the mound. To count these, we assumed that each small plaque represented one body. We geolocated drone footage and videos posted to social media, and counted the average number of plaques per square meter of trenches.

We studied both grave types in each of the five cemeteries. We then extrapolated the results to the remaining area in each cemetery.

We did not observe the use of trench-style graves to bury residents from Mariupol in any of the five cemeteries before the full-scale invasion began on February 24, 2022.

Analyzing the four other cemeteries

In Vynohradne cemetery, to the east of Mariupol, we estimate that 864 people were buried in both individual and trench-style graves. It is not clear whether any of those interred were combatants. Signs of new, longer trenches within Vynohradne cemetery were first visible on satellite imagery at the end of March 2022.

Novotroitske cemetery, to the northeast of Mariupol, contained 480 new individual graves, most of which were already visible on satellite imagery during the first week of March 2022. It is not clear whether any of those interred were combatants.

In Manhush cemetery, to the west of Mariupol, we counted 315 new individual graves as of October 12, 2022, and the cemetery did not expand until at least March 2023. It is not clear whether any of those interred were combatants.

The site expanded throughout April 2022. Some pits dug at that time still appeared empty as of March 2023.

We counted 45 new individual graves in the Pavlov Street cemetery, on the northern outskirts of Mariupol, all of which were dug between March 2022 and May 12, 2022. It is not clear whether any of those interred were combatants. The number of new graves could be much higher, however. We used the satellite image from May 2022 with the highest resolution, but vegetation cover and acquisition angles impeded further analysis.

In the other four sites, burials continued in June 2022 and beyond, as people reburied bodies recovered from makeshift graves and buildings.

The Uncounted

10,284 is likely a significant underestimate of the total number of people who died in Mariupol during this period. It is also unclear how many of these people were civilians and how many were combatants.

Some of the gravesites we identified may have contained multiple bodies. Some people may have died outside of the city after they managed to evacuate. Others buried in makeshift graves in the city may have never been transferred to larger cemeteries. Many bodies may have remained in the rubble of buildings or may never be found.

We encountered major limitations in our analysis due to the remote nature of our research.

Countless people who lost loved ones – spouses, children, friends, and neighbors – continue to look for their bodies in vain, with no knowledge of if or where they were buried.

Many say they will never stop looking.
