KYIV/IRPIN, Ukraine (Reuters) - The leaders of Germany, France and Italy, all criticised in the past by Kyiv for support viewed as too cautious, visited Ukraine on Thursday and offered the hope of EU membership to a country pleading for weapons to fend off Russia's invasion.
Air raid sirens blared in Kyiv as the visit by French President Emmanuel Macron, Germany's Olaf Scholz and Italy's Mario Draghi began, with the leaders touring a nearby town wrecked early in the war.
After holding talks with Ukrainian President Volodymyr Zelenskiy, the leaders signalled that Ukraine should be granted European Union candidate status, a symbolic gesture that would draw Kyiv closer to the economic bloc.
Scholz said Germany had taken in 800,000 Ukrainian refugees who had fled the conflict and would continue to support Ukraine as long as it needs.
"Ukraine belongs to the European family," he said.
On the battlefield, Ukrainian officials said their troops were still holding out against massive Russian bombardment in the eastern city of Sievierodonetsk, and described new progress in a counteroffensive in the south.
But they said battles on both main fronts depended on receiving more aid from the West, especially artillery to counter Russia's big advantage in firepower.
"We appreciate the support already provided by partners, we expect new deliveries, primarily heavy weapons, modern rocket artillery, anti-missile defence systems," Zelenskiy said after the talks with his European counterparts.
"There is a direct correlation: the more powerful weapons we get, the faster we can liberate our people, our land," he said.
Macron said France would step up arms deliveries to Kyiv, while NATO defence ministers meeting in Brussels were also expected to promise more weapons.
GAS FLOWS FALL
The visit had taken weeks to organise, while the three most powerful EU leaders all fended off criticism over positions described as too deferential to Russian President Vladimir Putin. Critics compared Macron and Scholz to Britain's Boris Johnson, who visited Kyiv more than two months ago.
The leaders, who were joined by Romanian President Klaus Iohannis, toured Irpin, a town northeast of the capital devastated soon after the invasion began on Feb. 24, where withdrawing Russian forces left behind bodies littering the streets.
Noting graffiti on a wall that read "Make Europe, not war", Macron said: "It's very moving to see that. This is the right message."
Scholz, Macron and Draghi all say they are strong supporters of Ukraine who have taken practical steps to reduce Europe's dependence on Russian energy and find weapons to help Kyiv.
But Ukraine has long criticised Scholz over what it regards as Germany's slow delivery of weapons and reluctance to sever economic ties with Moscow, and was furious this month at Macron for saying in an interview that Russia must not be "humiliated".
Italy, which last year sourced 40% of its natural gas imports from Russia, has also proposed a peace plan which Ukrainians fear could lead to pressure on them to give up territory.
After the talks in Kyiv, Macron said some sort of communication channel was still needed with Putin.
The war has caused global economic disruption and surging prices for food and energy, forcing central banks around the world to jack up borrowing costs even while their economies stumble.
Despite sanctions, Europe still depends on Russia for much of its energy supplies. Gas deliveries through a major pipeline to Germany have fallen in recent days, raising concern about supplies for winter, with Moscow blaming the sanctions for holding up delivery of equipment sent abroad for repair.
Germany said Russia's explanation was technically "unfounded" and was instead aimed at driving up gas prices. Italy said Moscow might be using the issue to exert political pressure.
'GHOST VILLAGES'
Ukraine is taking hundreds of casualties a day as the war has entered a brutal attritional phase in the east.
After Moscow launched its "special military operation" claiming its aim was to disarm and "denazify" its neighbour, Ukraine repelled an armoured assault on Kyiv in March.
Since then, however, Russia has shifted its aims and tactics, now trying to seize more ground in the east with advances behind massive artillery bombardments, and fortify its grip over captured territory in the south.
The main battle in recent weeks has been over the eastern city of Sievierodonetsk, where Ukrainian forces are holed up in a chemical factory with hundreds of civilians.
"Every day it becomes more and more difficult because the Russians are pulling more and more weapons into the city, and trying to storm it from several directions," Sievierodonetsk mayor Oleksandr Stryuk said on Thursday.
All remaining bridges linking the city with Ukrainian-held territory on the opposite bank of Siverskyi Donets river were destroyed in recent days, but Ukrainian officials say the garrison is still not completely cut-off.
An airstrike on Thursday hit a building sheltering civilians in Lysychansk across the river, killing at least three and wounding at least seven, regional governor Serhiy Gaidai said.
In the south, Ukraine says its forces have been making inroads into Kherson province, which Russia occupied early in its invasion. There has been little independent reporting to confirm battlefield positions in the area.
Zelenskiy's chief of staff, Andriy Yermak, tweeted that he had visited an area just 3-4 km from Russian positions, where dozens of "ghost villages" were depopulated by the combat.
"Our guys on the ground - the mood is fighting. Even with limited resources, we are pushing back the enemy. One thing is missing - long-range weapons. In any case, we will throw them out of the south," he wrote.
