On November 25, the Russian Defense Ministry said it had launched multiple coordinated attacks on key Ukrainian military infrastructure and dual-use facilities, including airports and energy facilities.
The attack involved tactical aircraft, many types of drones, missiles and artillery.
In addition to airports and energy facilities used to supply "users in the Ukrainian military industrial complex", about 138 Ukrainian military sites used to gather troops and equipment on the rear were also attacked, according to the Russian Defense Ministry.
While the Russian military did not specify the exact targets, Ukrainian media reported that Kiev, the southern port city of Odessa, the eastern city of Kharkov, and many other locations were affected.
According to Ukrainian estimates, the attack involved more than 100 Geran-2 suicide drones.
The new attack comes as the two sides appear to have intensified long-range attacks on each other. Kiev's recent use of long-range missile systems, such as the US ATACMS and the UK Storm Shadow missile, has prompted Moscow to use its all-new Oreshnik hypersonic ballistic missile.
The Oreshnik hypersonic missile was tested in combat last week and used in a surprise attack on Yuzhmash, a vast Soviet-era factory in the city of Dnepropetrovsk (called Dnipro in Ukraine).
Before the conflict, the plant mainly produced aircraft engines and missile components, and has been actively used by Kiev recently to refurbish and repair military equipment.
