The Times interviewed Russian soldiers who said they face a brutal fight to dislodge determined Ukrainian forces from a sliver of Russian land. Trapped civilians fear catastrophe.
At least 14 people were killed in Poltava, Ukrainian officials said, blaming Russia. Four died in Sudzha, a Russian town held by Ukraine, in a strike each country blamed on the other.
Ukrainian soldiers are describing fierce clashes as Russian forces try to retake territory in the Kursk region that could be key in eventual cease-fire talks.
President Volodymyr Zelensky said the soldiers were captured in the western Kursk region, where Ukraine has been fighting to hold on to territory it seized last summer.
