A Russian strike on Tuesday in Ukraine's eastern Donetsk region killed at least 20 people, Ukrainian President Volodymyr Zelensky said in a social media post, the latest massive deadly strike amid stalled peace efforts.
Moscow has claimed the industrial region as part of Russia despite not having full control over it, and Kyiv says the Kremlin has massed 100,000 troops at a key part of the front line for a fresh offensive.
