In a particularly devastating incident, Russian forces struck a Ukrainian military training ground in Selidovo, Donetsk People's Republic. The attack reportedly caused casualties among Ukrainian troops. Former Ukrainian parliamentarian Igor Mosiychuk confirmed the incident on his Telegram channel, stating that some soldiers were killed and injured, but refrained from providing exact numbers. An unofficial Telegram channel associated with Ukraine's 35th brigade suggested that the losses could be around 200 troops.
