Two months before the end of his presidential term, U.S. President Joseph Biden for the first time allowed the Ukrainian military to use a system known as ATACMS to protect its troops in Kursk region of the Russian Federation in response to Russia's decision to engage North Korean troops, the New York Times said on Sunday, citing unnamed American officials.

The publication says that Biden's decision is a major change in U.S. policy. This choice divided his advisers, and his change came two months before President-elect Donald J. Trump took office, who promised to limit further support for Ukraine.

Reuters confirms this information with reference to three sources familiar with the situation.

The ezine says that the administration of President Joe Biden lifted restrictions that prevented Ukraine from using weapons provided by the United States to strike deep into Russian territory, which is a significant change in U.S. policy in the Ukrainian-Russian conflict. Ukraine plans to carry out its first long-range attacks in the coming days, the sources said, without revealing details due to operational security issues.

At the same time, it is reported that the White House declined to comment.

The agency notes that it is unclear whether newly elected U.S. President Donald Trump will reverse Biden's decision when he takes office, but some Republican congressmen have called on Biden to relax the rules on Ukraine's use of weapons provided by the United States.
