At least seven people were killed and 27 injured across Ukraine overnight into Tuesday as Russia continued long-range attacks on cities, local officials said.

Russia's overnight attacks killed one person in Ukraine's northeastern region of Kharkiv and injured several more in the northern city of Chernihiv, regional Ukrainian officials said on Tuesday.

With 41 military aircraft impacted, the Ukrainian drone attack was described by some commentators as Russia's "Pearl Harbor." The attack on Pearl Harbor in December 1941 was a surprise air raid by Japan on the U.S. during World War II. Kyiv's assault follows ground advances by Moscow troops in recent days in Ukraine's Sumy border region.
