On the local date, according to Reuters, three informed sources said that the Biden administration of the United States has lifted the restriction that prohibited Ukraine from using U.S.-provided weapons to attack deep targets within Russia, marking a significant shift in U.S. policy regarding the Russia-Ukraine conflict.

Russia has warned that if restrictions on the use of U.S. weapons in Ukraine are relaxed, it will view this move as a "significant escalation." Sources say that Ukraine plans to carry out its first long-range attack in the coming days, which is likely to use the Army Tactical Missile System (ATACMS).

It is reported that Ukrainian President Zelensky has been requesting for months that the United States allow the Ukrainian military to use American weapons to strike Russian military targets far from its borders.

Zelensky responds: Such things will not be announced in advance. In response to media reports that Ukraine has been granted permission to use long-range weapons to strike deep into Russia, Zelensky stated in his regular video address, "Today, there are many reports in the media about us obtaining permission for related actions. However, strikes are not achieved through words. Such things will not be announced in advance. The missiles will make their own statement."

Russian Warning: Could Lead to Severe Escalation of Situation On the mentioned date, when responding to the news that the US government has allowed Ukraine to use US weapons to attack deep targets within Russia, the Chairman of the International Affairs Committee of the Russian State Duma, Slutsky, stated that using US-made missiles to carry out deep strikes on Russia would inevitably lead to an extremely severe escalation of the situation, potentially resulting in even more serious consequences. The Biden administration cannot be unaware that what they are leaving for the Trump team is not just the resolution of the Ukraine conflict, but also the prevention of global confrontation.

On the same day, Dmitry Sablin, First Deputy Chairman of the International Affairs Committee of the Federation Council (upper house of the Russian parliament), said in an interview that the US authorizing Ukraine to use US-made missiles for deep strikes against Russia is an unprecedented step, and Russia will respond immediately to this.
