Ukraine president issues rebuke to Donald Trump’s running mate JD Vance who has pushed for negotiations with Russia

Ukraine’s offensive in Russia’s Kursk region had killed at least 31 civilians and injured 256 as of 5 September, the Russian foreign ministry has said. These figures have not yet been verified by the Guardian.

Kyiv launched its Kursk offensive on 6 August in a bid to pull Moscow’s forces away from eastern Ukraine, where the Russian army has captured a string of villages in recent months.
