Defense authorities assert that Russian forces are employing weaponry with the potential to cause mass casualties as they attempt to capture eastern Ukraine.
Russian bombers have likely launched massive anti-ship missiles from the 1960s in Ukraine, according to the UK Ministry of Defence and Ukrainian sources.
The primary purpose of the Kh-22 missiles was to destroy aircraft carriers with a nuclear bombs. Officials warned that when utilized in conventional ground operations with traditional weapons, they are "extremely inaccurate and therefore can cause severe collateral damage and casualties."
In what has become a battle of attrition for the eastern region of coal mines and industry known as the Donbas, both sides have squandered vast quantities of weaponry, inflicting enormous pressures on their resources and inventories.
According to officials, Russia is likely utilizing anti-ship missiles because it lacks modern, more precise weapons.
In the meantime, a Ukrainian regional governor has accused Russia of employing incendiary weaponry in the town of Vrubivka in eastern Luhansk province, southwest of the hotly fought cities of Sievierodonetsk and Lysychansk.
Although using flamethrowers on the battlefield is permissible, Serhii Haidai, the governor of the province of Luhansk, claimed the strikes on Friday night and Saturday caused extensive damage to civilian infrastructure.
Mr. Haidai posted on Telegram on Saturday morning, "Specifications are being made regarding the number of victims in Vrubivka, Popasnyanska district. The adversary utilized a flamethrower rocket system at night, destroying many homes.
He also reported that Russian forces continued their attack on Sievierodonetsk and destroyed vital industrial infrastructure in neighboring Lysychansk, including railway depots, a brick factory, and a glass plant.
He stated, "(Russians) are destroying world-renowned factories." "Thousands of people of Sievierodonetsk dream of returning and crossing the first checkpoint at Azot (a chemical facility), but the enemy is destroying the city and the chemical industry.
Women, children, and the elderly have evacuated the heavy fighting in eastern Ukraine on a special evacuation train that departed from Pokrovsk and went west.
Svitlana Kaplun, whose family fled as shelling reached their Krasnohorivka neighborhood, stated, "We are now on the front line. The children are constantly anxious and terrified to sleep at night, so we decided to take them outside.
In the early days of the conflict, following a failed attempt to seize control of the Ukrainian capital, Russia moved its focus to the Donbas, an eastern region with coal mines and industries.
Since 2014, the region that borders separatists backed by Moscow has partially governed Russia.
The battle has increased casualties and new requests from Ukraine for more armaments from the West.
In an interview broadcast by the BBC on Thursday, Mykhailo Podolyak, military adviser to the president of Ukraine, stated that the daily loss of 100 to 200 Ukrainian soldiers is due to a "complete lack of parity" between Ukraine and Russia.
He stated that only more modern Western armaments could halt the Russian invasion and force Moscow to negotiate.
The conflict in the Donbas has been ongoing for over two months. A provincial governor stated that Russian and Ukrainian soldiers fought "for every house and every street" in Sievierodonetsk, which has been under constant siege recently.
Sievierodonetsk lies in the final area of the Luhansk region, not yet seized by Russia or separatists supported by Russia. Together, the Luhansk and Donetsk regions comprise the Donbas.
