Two US sources familiar with the situation said President Joe Biden has permitted Ukraine to use US weapons inside Russia for the specific goal of defending Kharkiv. The officials emphasised that the US policy, which calls on Ukraine not to deploy long-range missiles and other munitions provided by the US to launch offensive strikes inside Russia, has not changed. The officials made this request while speaking about the sensitive subject. The action is being taken in response to increased requests from Ukrainian officials to the US administration to permit their forces to protect themselves against attacks coming from Russian territory.

Politico was the first to report on Biden's decision. On Thursday, US Secretary of State Antony Blinken attacked Russian efforts to foment unrest in democracies through disinformation, implying that the Biden administration may soon permit Ukraine to launch an internal attack within Russia using US-supplied weaponry. Blinken met with NATO foreign ministers in Prague after more officials said that Ukraine should be able to defend itself by attacking targets in Russian territory. He declared that Moscow's use of disinformation and misinformation was "poison" and signed a counter-agreement with the Czech government. He also toured a Czech military base, where he saw armoured vehicles that Prague is sending to Kyiv to help fight Russia's invasion and received a briefing on a Czech initiative to supply Ukraine with a million rounds of ammunition by the end of the year.
