Ukraine's top military commander Oleksandr Syrskyi warned on Saturday of a possible new Russian offensive in the Kharkiv region, a part of northeastern Ukraine which has seen heavy fighting since Russia invaded in 2022.

KYIV, Ukraine (AP) — Waves of drones and missiles targeted Kyiv overnight in the largest aerial assault since Russia’s invasion of Ukraine began more than three years ago, officials said Friday, amid a renewed Russian push to capture more of its neighbor’s land.

Ukraine said Saturday it struck an airbase in Russia, which continued overnight to use hundreds of drones in its stepped-up bombing campaign. The fresh wave of attacks signal a breakthrough isn't expected anytime soon in efforts to end the more than three-year-old war.
