Russia attacked cities across Ukraine with hundreds of drones and a missile strike, hitting energy infrastructure and wounding at least 15 people.

Despite the changes in warfare, Russian forces retain the ascendancy and are making slow but steady advances in the east and north of Ukraine. Russia has also caught up in UAV technology after falling behind early in the war, according to military analysts, and like its enemy is churning out drones domestically at a rate of millions a year.

Russia has launched overnight attacks on four Ukrainian cities, injuring at least 15 people and targeting energy infrastructure.
