Ukraine pushes offensive against Russia

KYIV — Ukraine sustained its major cross-border incursion into Russia, where state media and local officials reported early Friday a fire at a military airfield and "massive" drone attack hundreds of kilometers from the border.

The cross-frontier offensive in Kursk region over the past few days appears to be the most significant attack on Russian soil since the war in Ukraine began, involving around 1,000 troops and more than two dozen armored vehicles and tanks, according to the Russian army.
