In recent days, the Ukrainian army has been successful in reclaiming large swaths of seized land, which has resulted in the withdrawal of Russian soldiers.
In the Kharkiv area, according to President Volodymyr Zelensky, his troops are now strengthening their grip over 8,000 square kilometres (3,088 square miles) of retaken land.
Joe Biden, the Vice President of the United States, referred to Ukraine’s progress as “substantial.”
Mr. Biden said that it was “obvious” that the advance had been successful, but he also warned that the attack “may be a long haul.”
Despite the fact that Russia still maintains control over around one fifth of Ukraine’s landmass, cities in the Donbas that came into Russian hands early on in the conflict are now under danger from the advancing troops of Kyiv.
After failing to take towns throughout the nation, including the capital city of Kyiv, Russia’s attention has been focused on the Donbas region. Portions of the Donbas were already under the control of separatists supported by Russia before Russia’s invasion began this year.
Exiled Ukrainian leader Serhiy Hayday of the Luhansk area, which is one of the two provinces that make up the Donbas, said that Ukrainian troops had reached the strategically important town of Lyman.
In a telegram dispatch, Mr. Hayday was quoted as saying, “There are tremendous fighting going on in Lyman right now, and I expect they will endure for a few more days.”
After a well-protected combat at the end of May, Lyman was ultimately taken by Russian troops. It is just around 50 kilometres (31 miles) away from Donetsk, the self-proclaimed capital of the Donetsk People’s Republic, which serves as its neighbour to the west.
Its seizure by Russian forces was a major victory, since it gave Moscow control of an important route running east to west.
In other regions, Ukrainian forces are said to have reached the Russian border, and Mr. Hayday said that their capture of two towns, Izyum and Kupiansk, could result in the supply lines leading to the Russian-held cities of Severodonetsk and Lysychansk being severed. Both of these cities are currently under Russian control.
The BBC has not independently confirmed the extent to which Ukraine has improved its position.
Allegations of Russian war crimes have begun to surface as Ukrainian troops advance farther into territory that was once held by Russia.
During the time when Russian soldiers occupied the town of Balakliya, locals in the town informed the BBC that the Russian military had tortured people inside the town’s police station. Others described being electrocuted while they were being held in jail.
