Ukrainian President Volodymyr Zelensky said a counteroffensive "will happen," declining to give details on when it'll start. Russia has already built up multiple layers of defense, satellite imagery shows. The southern town of Nova Kakhova is under "severe artillery fire" by Ukrainian forces, according to Russian-installed local officials . Rescuers are done searching an apartment block where at least 23 people — including six children — were killed by a Russian strike Friday in the city of Uman, according to Ukrainian officials. Two missing residents are presumed dead, local police say.
