Russia pressed on with its offensive in eastern Ukraine on Thursday after NATO branded Moscow the biggest "direct threat" to Western security and agreed plans to modernise Kyiv's beleaguered armed forces.
Ukrainian authorities said they were trying to evacuate residents from the frontline eastern city of Lysychansk, the focus of Russia's attacks where about 15,000 people remained under relentless shelling.
"Fighting is going on all the time. The Russians are constantly on the offensive. There is no let-up," regional Governor Serhiy Gaidai told Ukrainian television.
Russian troops had attacked the Lysychansk oil refinery on Thursday morning, Gaidai later wrote on Telegram.

The ambassador of the self-proclaimed Luhansk People's Republic told Russia's RIA news agency the Lysychansk oil refinery was now fully controlled by Russian and pro-Russian forces, and all roads to Lysychansk were also under their control.
Russian forces are trying to encircle Lysychansk as they seek to capture the Donbas region, which comprises Donetsk and Luhansk provinces.
At a summit on Wednesday dominated by Russia's invasion of Ukraine and the geopolitical upheaval it has caused, NATO invited Sweden and Finland to join and pledged a seven-fold increase from 2023 in combat forces on high alert along its eastern flank.
In reaction, President Vladimir Putin said Russia would respond in kind if NATO set up infrastructure in Finland and Sweden after they join the U.S.-led military alliance.
Putin was quoted by Russian news agencies as saying he could not rule out that tensions would emerge in Moscow's relations with Helsinki and Stockholm over their joining NATO.
U.S. President Joe Biden announced more land, sea and air force deployments across Europe from Spain in the west to Romania and Poland bordering Ukraine.
These included a permanent army headquarters with accompanying battalion in Poland - the first full-time U.S. deployment on NATO's eastern fringes.
"President Putin's war against Ukraine has shattered peace in Europe and has created the biggest security crisis in Europe since the Second World War," NATO Secretary-General Jens Stoltenberg told a news conference, committing to put 300,000 NATO troops on high readiness from 2023. "NATO has responded with strength and unity."
Britain said it would provide another 1 billion pounds ($1.2 billion) of military support to Ukraine, including air defence systems, uncrewed aerial vehicles and new electronic warfare equipment.
UKRAINE PLEADS FOR MORE WEAPONS
As the 30 national NATO leaders were meeting in Madrid, Russian forces intensified attacks in Ukraine, including missile strikes and shelling on the southern Mykolaiv region close to front lines and the Black Sea.
The mayor of Mykolaiv city said a Russian missile had killed at least five people in a residential building there, while Moscow said its forces had hit what it called a training base for foreign mercenaries in the region.
Attacks on the northeastern city of Kharkiv continued, Ukraine's military said, with shelling from tanks, mortars and missiles.
Video showed police and emergency workers examining the destroyed remains of a factory and damaged residential buildings in Kharkiv on Wednesday.
“Where, why and what they (Russians) targeted is unclear, yet. We are figuring out where they aimed because there are no military units in that area,” Volodymyr Tymoshko, chief of Kharkiv region police told Reuters.
In the southern Kherson region, Ukrainian forces were fighting back with artillery strikes of their own, Oleskiy Arestovych, adviser to the Ukrainian president, said in a video posted online.
A video clip aired on Russia's RIA state news agency showed former U.S. soldier Alexander Drueke, who was captured while fighting for Ukrainian forces.
"My combat experience here was that one mission on that one day," said Drueke, from Tuscaloosa, Alabama, referring to the day he was captured outside Kharkiv, Ukraine's second-largest city. "I didn't fire a shot. I would hope that would play a factor in whatever sentence I do or don't receive."
President Volodymyr Zelenskiy once again told NATO that Ukrainian forces needed more weapons and money, and faster, to erode Russia's huge edge in artillery and missile firepower, and said Moscow's ambitions did not stop at Ukraine.
The Russian invasion that began on Feb. 24 has destroyed cities, killed thousands and sent millions fleeing. Russia says it is pursuing a "special military operation" to rid Ukraine of dangerous nationalists. Ukraine and the West accuse Russia of an unprovoked, imperial-style land grab.
The top U.S. intelligence official Avril Haines said on Wednesday the most likely near term scenario is a grinding conflict in which Moscow makes only incremental gains, but no breakthrough on its goal of taking most of Ukraine.
'FULL SOLIDARITY'
In a nod to the precipitous deterioration in relations with Russia since the invasion, a NATO communique called Russia the "most significant and direct threat to the allies' security", having previously classified it as a "strategic partner".
NATO issued a new Strategic Concept document, its first since 2010, that said a "strong independent Ukraine is vital for the stability of the Euro-Atlantic area".
To that end, NATO agreed a long-term financial and military aid package to modernise Ukraine's largely Soviet-era military.
"We stand in full solidarity with the government and the people of Ukraine in the heroic defence of their country," the communique said.
