Arms exhibition near Kyiv was hit by a Russian ballistic missile, killing at least 10 people and injuring about 100, with officials noting the venue may have been inadequately publicized and prompting criminal probes into safety and organizational decisions. Zelensky warned of a potential fresh massive Russian strike within 48 hours amid ongoing air-raid alerts. The attack followed a pattern of strikes on defence industry targets and other civilian sites, with additional fatalities reported in Sloviansk and strikes on Russian facilities, including a Kirov military components plant. Kyiv claimed responsibility for striking Wildberries warehouses near Saint Petersburg, alleging drone-component storage and military support ties to Russia, while Russia accused Ukrainian UAV exhibitions of being used to attack civilians. The broader toll of the war continued to rise, with long-range strikes that sent mixed signals about escalation, mobilization plans, and the possibility of reaching a diplomatic stalemate.
