Several European leaders have spoken in Kyiv with Ukrainian President Volodymyr Zelenskyy.
In the face of an intensifying Russian offensive in the east, they conveyed a clear message that the European Union stands together in helping Ukraine.
French President Emmanuel Macron, German Chancellor Olaf Scholz, Italian Prime Minister Mario Draghi and Romanian President Klaus Iohannis met with Zelenskyy on Thursday.
They also visited Irpin on the outskirts of the capital.
Scholz accused Russia of pushing forward a terrible war with what he called the utmost brutality.
He said the war must be brought to an end by means of European aid and sanctions.
Russian forces continue their attacks in a bid to put all of the Luhansk region under their control.
They are trying to seize Severodonetsk. It's the Ukrainian military's last stronghold in the region.
The military said on Wednesday that Russia's main strike forces were trying to attack the city in nine directions all at the same time. The region's governor says about 10,000 civilians remain there.
EU, G7 and NATO summits are scheduled for the coming weeks. The leaders will discuss Ukraine's bid to join the EU, as well as military and economic support for the country.
