What the claims over Kursk casualties showed on 23 September 2024
A look back at a day of competing accounts of civilian harm, set against European financing and nuclear plant warnings.

What happened on 23 September 2024, and why did the accounts of it diverge so sharply? On that date the Russian Foreign Ministry reported that at least 56 Russian civilians had been killed and 266 others injured by Ukraine's Armed Forces in Kursk Oblast. The Ukrainian Foreign Ministry denied the claim and dismissed it as Russian propaganda.
The figures belonged to the 2024 Kursk offensive, and the two ministries gave directly opposed readings of them. One side presented a toll of dead and wounded; the other rejected the allegation outright.
The days before
The preceding days had already produced a series of claims and counterclaims. On 18 September 2024, a Ukrainian drone attack on a Russian weapons depot in Toropets, Tver Oblast, caused an explosion large enough to be detected as an earthquake by monitoring stations. Residents were told to evacuate, and schools in the region were closed.
On 20 September 2024, Russian management at the Zaporizhzhia Nuclear Power Plant accused Ukraine's Armed Forces of endangering the plant's safety by launching a drone at a nearby electrical substation.
The same day brought a financial signal from Brussels. European Commission President Ursula von der Leyen announced a loan of up to €35 billion (US$39 billion) for Ukraine in military and energy support. The announcement followed Ukrainian President Volodymyr Zelenskyy's drafting of a new victory plan against Russia.
A pattern of contested narratives
Taken together, these reports show how much of the public record of the war rested on statements from the parties themselves. Moscow's ministry, the plant's Russian management and Kyiv's foreign ministry each put forward their own versions. The European funding announcement was a different kind of item: a stated commitment of money rather than a disputed claim.
By 23 September 2024, the Kursk casualty figures were therefore one more assertion in a contested information space, issued by one government and rejected by another.
