Ukraine has accused Russia of retaliating for its retreat in the east by targeting civilians, nuclear power plants and other infrastructure.
On Sunday, Ukraine claimed to have pushed Russian troops back from the eastern part of Kharkiv, while Russia said the troops were withdrawn to reorganize.

President Volodymyr Zelenskiy wrote in a late-night tweet on Sunday, "They have no military goals but to deprive people of electricity and heating."
Ambassador of Ukraine to the United States Bridget Brink has also condemned the Russian attacks.
According to him, Russia is raining missiles on these areas after liberating cities and villages from Ukraine.
Moscow, on the other hand, has denied that its forces are deliberately targeting civilian areas.
President Zelensky called the assault on the Russian army in the southeast a major success in six months and said more gains would be made in the winter as Kiev received powerful weapons.
On Sunday, Ukraine hailed it as its main victory in the six-month war, saying that not only had Russian troops withdrawn from the area, but they had also left behind huge amounts of weapons and other equipment.
After that, the Russian Ministry of Defense said that the decision to withdraw troops from Balaklia and Azyum in the Kharkiv region was made to reorganize the existing forces in Ukraine to increase operations on the Donetsk front.
According to experts, the current situation is crucial in the months-long battle, as most of the eastern flank was occupied by Moscow.

On the other hand, the current situation is being declared as the main 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.
According to him, "I therefore repeat that the more weapons we get, the faster we will win and the sooner the war will end."
On Saturday night, Ukrainian President Volodymyr Zelenskyi said in his speech that "our army has taken over two thousand square kilometers of occupied territory as a result of the counterattack that started at the beginning of this month."
Similarly, Zelinsky's chief of staff, Andrey Yermark, has quipped that the Russian army claims to be the fastest army in the world, but on the run. Keep running.
