Ukraine has said it aims to liberate all of its territory after pushing back Russian forces in the country's northeast.
According to the news agency Reuters, on Tuesday, Ukraine called on the West to speed up the supply of weapons to continue the offensive.
The abandonment of key territory by Russian forces in northeastern Ukraine marks Russia's worst defeat since the war.
The Ukrainian army has recaptured several areas from the Russian army.

Ukrainian President Volodymyr Zelenskyi called the offensive against Russian forces in the southeast a major success in six months and said more gains would be made in the winter as Kiev received powerful weapons.
Russia, on the other hand, has said that it has launched large-scale attacks on the Ukrainian army.
Russia announced the withdrawal of its troops from the northeastern part of Ukraine, especially Kharkiv.
The current situation is being described as a major success of Ukraine, which also shows that it is taking full advantage of the weapons that are being supplied to it by Western countries.
Ukraine's Foreign Minister Dmytro Koliba says that Ukraine's armed forces have proven that they are capable of defeating Russia thanks to the weapons they are providing.
