A Russian attack cut power to a large part of Ukraine’s southern Black Sea region of Odesa, while strikes on the Ukrainian capital Kyiv entered their seventh day, Ukrainian officials said yesterday.

Meanwhile, Russia vowed to head off any disruption to civil aviation yesterday after a warning by Ukrainian President Volodymyr Zelensky that its drones had made Russian airspace dangerous to use. We want to warn every airline that uses Russian airspace, every insurer, everyone who still uses key Russian airports: the Russian sky is becoming completely dangerous,” Zelensky said.
