A Russian strike has hit a crowded market in the Ukrainian city of Kostiantynivka, killing at least 17 people, as the US secretary of state, Antony Blinken, was in Kyiv for an unannounced visit, his first for a year to the Ukrainian capital.
Ukrainian officials said a further 32 people were wounded in the attack, one of Russia’s deadliest attacks in months, 12 miles (20km) from the frontlines in the Donetsk region of eastern Ukraine.
