Russia and Ukraine struck each other with hundreds of drones on Sunday, throwing Russian air travel in disarray, shortly after Ukrainian President Volodymyr Zelenskyy announced deals with Western partners that would allow Kyiv to scale up drone production.

Ukraine’s Ministry of Defense is claiming that more than 800 Russian soldiers were killed over the weekend, along with the destruction of dozens of armored vehicles.

At least three children were among 27 people wounded as a result of a Russian drone attack on Ukraine's second-largest city of Kharkiv overnight that damaged apartments and a kindergarten, Ukrainian authorities said on Monday.
