Ukraine has hit Russia in another sweeping wave of overnight aerial attacks, especially targeting industrial facilities and energy infrastructure across multiple regions, and the extent of damage is yet to be disclosed.

One of the key targets was reportedly the VNIIR-Progress plant, located in the republic of Chuvashia, which is alleged by Ukraine and the West to manufactures components for Russian drones and bombs. Other nearby infrastructure was also attacked.

Ukraine has for months been making clear that it is going gloves off when it comes to attacking Russia's energy and military sites, as well as dual use military-industrial factories. Ukraine used its domestic-made Flamingo cruise missile:

Ukrainian forces have carried out a missile attack deep inside Russia, hitting a major military plant overnight, President Volodymyr Zelensky has said.

He said FP-5 Flamingo cruise missiles struck the drone and missile plant in the city of Cheboksary, in the Chuvash Republic, more than 900km (560 miles) from the front line. Local officials say said three people were injured in a missile attack on the city.

Ukraine also said it had hit the Moscow-occupied port of Mariupol on the Sea of Azov, a Russian oil refinery in Samara and a "shadow fleet" oil tanker in the Black Sea.

According to a review of sensitive sites struck in the fresh overnight attack wave:

• In Novokuibyshevsk in Russia’s Samara oil hub region, hosting Rosneft refineries, regional governors said authorities repelled drone attacks while urging one million residents to seek shelter. Russian OSINT channel Astra confirmed the Kuibyshevsk oil refinery was burning after at least 29 drones attacked.
• In Russia’s Rostov region bordering Ukraine, falling debris from a drone triggered a fire in a fuel tank at a civilian site. In the central Vladimir region, two industrial facilities were ablaze.
• Rare air raid alerts were issued in remote oil-producing regions Khanty-Mansiysk, Perm and Tyumen, plus industrial Ural mountain regions Chelyabinsk and Sverdlovsk.

Chuvashia regional governor Oleg Nikolayev blasted the strike on the aforementioned manufacturing plant as indicative of the "impotent rage of terrorists who, having no success at the front line, try to intimidate peaceful people in the rear."

All of these strike waves in disparate places is likely invite even greater airstrikes on Kiev, after the capital has already been hit hard over the past several weeks.

President Putin and top military brass had last month said strikes would be initiated against "decision-making centers" in response to the dorm attack in the Russia’s Lugansk People’s Republic on May 22, which killed 21 people - mostly teenage girls - and injured 70 others.

Kremlin officials now say that Russian forces have "a right to dismantle any infrastructure that supports terrorism."

But it's also these constant attacks on oil and industrial sites that little by little will put immense strain on Russia's economy and the populace. The salvos out of Ukraine will keep coming, especially as Moscow continues to maintain the 'special military operation' at a slow, grinding pace.
