Kyiv, June 11 (PTI/AP): Ukrainian and British officials warned on Saturday that Russian forces are relying on weapons with the potential to cause mass casualties as they try to make headway in capturing eastern Ukraine.
Russian bombers have likely been launching heavy 1960s-era anti-ship missiles in Ukraine, the UK Defence Ministry said.
The Kh-22 missiles were primarily designed to destroy aircraft carriers using a nuclear warhead. When used in ground attacks with conventional warheads, they are highly inaccurate and therefore can cause severe collateral damage and casualties, the ministry said.
Both sides have expended large amounts of weaponry in what has become a grinding war of attrition for the eastern region of coal mines and factories known as the Donbas, placing huge strains on their resources and stockpiles.
Russia is likely using the anti-ship missiles because it is running short of more precise modern missiles, the British ministry said in a daily update.
It gave no details of where exactly such missiles are thought to have been deployed and there was no immediate confirmation from Ukrainian authorities of the use of the 5.5-tonne (6.1-ton) missiles.
A Ukrainian regional governor has accused Russia of using incendiary weapons in the village of Vrubivka in Ukraine's eastern Luhansk province, southwest of the fiercely contested cities of Sievierodonetsk and Lysychansk.
While the use of flamethrowers on the battlefield is legal, Serhii Haidai, governor of Luhansk province, alleged the attacks overnight caused widespread damage to civilian facilities.
Information about the number of victims in Vrubivka, in the Popasnyanska district, is being specified. At night, the enemy used a flamethrower rocket system - many houses burnt down, Haidai wrote on Telegram on Saturday morning.
He also said that Russian forces continued their assault on Sievierodonetsk and were destroying critical industrial facilities, including railway depots, a brick factory and a glass factory in neighbouring Lysychansk.
(Russians are) destroying world-famous factories. Thousands of Sievierodonetsk residents dream of returning and crossing the first checkpoint at Azot (a chemical plant), but the enemy is destroying both the city itself and the chemical industry, he said.
The accuracy of Haidai's claims could not be immediately verified.
European Commission President Ursula von der Leyen says she is in Kyiv to meet with Ukrainian President Volodymyr Zelenskyy.
Von der Leyen said on Twitter that they will take stock of the joint work needed for reconstruction and of the progress made by Ukraine on its European path .
The European Commission, the EU's executive arm, is expected to deliver next week an opinion on Ukraine's request to be granted EU candidate status, a first step on the long path toward membership.
Von der Leyen is making her second visit to Ukraine since Russia invaded its neighbour. She was one of the first European leaders to go to Ukraine during the war.
Nearly 800 children have been killed or injured in Ukraine since the beginning of Russia's invasion, Ukrainian authorities said on Saturday.
According to a statement by the Office of the Prosecutor General of Ukraine, at least 287 children died as a result of military activity, while at least 492 more have been injured.
The statement stressed the figures were not final and said they were based on investigations by juvenile prosecutors.
The officer said children in Ukraine's Donetsk province, which together with Luhansk makes up the Donbas, suffered the most, with 217 reported killed or injured, compared with 132 and 116, respectively, in the Kharkiv and Kyiv regions.
The Ukrainian army said on Saturday that Russian forces were regrouping to launch an offensive on the Donetsk province city of Sloviansk.
Moscow-backed rebels have controlled self-proclaimed republics in both Donetsk and Luhansk since 2014, and Russia is trying to seize the territory still under Ukrainian control.
In its regular operational update, the General Staff of the Armed Forces of Ukraine said Russian soldiers managed to get a foothold overnight in the village of Bohorodychne, 24 kilometres northwest of Sloviansk, and were preparing to attack the city.
The Donetsk regional police said Russian missiles hit 13 towns and villages in the province overnight.
In a statement, the police said that civilians had been killed and wounded, without specifying numbers. Donetsk and Luhansk make up the Donbas.
The Ukrainian army's update said that the threat of missile and airstrikes on Ukraine from Belarus remains, noting that the Belarusian government extended military exercises along the Ukrainian-Belarusian border until June 18.
Four civilians died and two were wounded as a result of Russian shelling of Ukraine's northeastern Kharkiv region on Friday, regional emergency services said on Saturday.
According to the press service of the Main Directorate of the State Emergency Service in the Kharkiv region, a Russian shell destroyed a private house in the town of Chkalovske, killing four people.
Another two were injured in massive shelling of private homes in Derhachi, on the outskirts of the regional capital, Kharkiv, it said.
The Kharkiv region, home to Ukraine's second-largest city, is north of the Donbas.
Elsewhere, the governor of Ukraine's central Dnipropetrovsk region said Russian shelling injured two civilians Friday night. Valentyn Reznychenko said in a Telegram post that the two were hospitalised. (AP)
