At least 10 Ukrainian drones were shot down on their approach to Moscow overnight into Sunday morning, according to the city's mayor, with temporary restrictions introduced at two of the capital's airports.

Russia launched a massive attack on Ukraine's Kharkiv, killing four and injuring dozens. President Zelenskyy condemned the violence and appealed for urgent air defense assistance.

A surprise Ukrainian drone attack that targeted Russian air bases hosting nuclear-capable strategic bombers was unprecedented in its scope and sophistication.
