Ukrainian strikes hit arms factory and oil refinery deep inside Russia

Ukraine says an arms factory and an oil refinery deep inside Russia are among the targets it has hit in a fresh wave of attacks.

But Russian drone attacks on Ukraine had left one person dead and more than a dozen people injured, officials said.

Ukrainian president Volodymyr Zelenskyy revealed Ukraine had hit the military plant on Tuesday night in the western Russian city of Cheboksary - in the region of Chuvashiya - with Ukrainian-made Flamingo cruise missiles.

He said the factory, more than 550 miles behind the front line, supplied components for Russian drones and missiles.

Forces had also targeted an oil refinery in Samara, in the southwestern part of Russia, he said.

Samara governor Vyacheslav Fedorishchev said that several industrial plants were damaged by drone strikes and three people were injured.

Oleg Nikolayev, the head of Chuvashiya, confirmed the missile attack in Chuvashiya without giving any further details.

The Astra online news outlet said the Ukrainian strike had hit the military complex, which it reported produces antennas for drones.

Russia's defence ministry said its forces had managed to intercept 326 Ukrainian drones overnight.

Ukraine's military said on Wednesday it had also struck the West Horizon tanker in the Black Sea, which it described as being a part of the Russian "shadow fleet".

It comes after Ukraine had revealed a drone attack had targeted the ‌Russian-occupied port of Mariupol, leaving the site with limited capacity.

Kyiv's ‌drone forces said the port ‌was without power after strikes on its energy, ⁠repair and ​management infrastructure.

In a statement, Ukraine added the ​attack had "significantly limited" Mariupol's ⁠use as ⁠a military logistics ​hub by the Russians.

Mariupol is a strategically important port city on the Sea of Azov, in the southeast of Ukraine, and was secured by Russian forces in 2022.

"The port was used ‌by the enemy for military logistics, as well as the illegal export of ‌Ukrainian grain, coal and metal to Russia," it said.

Ukrainian drones also hit a historic museum in Sevastopol in Crimea, according to officials.

The museum commemorates the 1853-1856 Crimean War between the Russian Empire and a coalition ​that included the Ottoman Empire.

Sevastopol's Russian-installed ‌governor, Mikhail Razvozhayev, said the museum's roof had caught fire and called the attack "sacrilege". He said a huge panorama painting depicting the defence of the city during the Crimean War by artist Franz Rubo was effectively destroyed.

The strikes are part of a mounting Ukrainian campaign to target ⁠Russian military logistics far ​behind the front line, which ​analysts say is hampering Moscow's battlefield advances.

Russia is also starting to face frequent Ukrainian attacks on its oil infrastructure.

​Ukrainian drone attacks have constricted supplies from Russia, while international sanctions have ‌made crude exports more costly.

Residents in Russian-controlled Crimea were dealing with fuel rationing on Wednesday, the Reuters news agency reported.

The agency said it had also been told of shortages of sugar in some shops with limits on the purchase of buckwheat, a Russian staple.

One person was killed and 15 others were injured in eastern Ukraine over the past 24 hours, officials said.

A barrage of 26 drones struck the city of Kharkiv on Wednesday, injuring at least four people, according to regional administration head Oleh Syniehubov.

In Zaporizhzhia and the surrounding region, 10 people were injured overnight in a series of Russian aerial attacks, according to regional head Ivan Fedorov.

In Odesa, a mother and two young children required medical attention after Russian drones damaged two residential buildings, according to regional administration head Oleh Kiper.
