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 Zelensky, the leaders signalled that Ukraine should be granted EU 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.

“We appreciate the support already provided by partners, we expect new deliveries, primarily heavy weapons, modern rocket artillery, anti-missile defence systems,” Zelensky 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.
