Reports state that the United States is believed to have modified its policies solely to defend the Kharkiv region.
It happens as Ukrainian leaders are pressing the US government to give their soldiers permission to repel Russian attacks.
As Russia has stepped up its attacks in the northeastern Kharkiv region, Ukrainian President Volodymyr Zelenskyy and others have become more outspoken in their argument that the restriction was placing Ukrainian forces in an unworkable situation.
Russia advanced in the region when the US military’s supply of help was drawn down gradually and while the insufficient military production in western Europe delayed vital supplies to it.
The second-biggest city in Ukraine, Kharkiv, lies only 20 kilometers (12 miles) from the Russian border.
However, US officials emphasized that US policy has not changed, which calls on Ukraine to refrain from using US long-range missiles and other weapons to launch aggressive strikes inside Russia.
The US secretary of state, Antony Blinken, had alluded to the policy shift earlier on Thursday during a NATO foreign ministers’ meeting in Prague.
There, Putin denounced as “poison” Moscow’s use of disinformation and misinformation and signed a counteragreement with the Czech government.
