The White House has resisted sending Kiev missiles with the range to hit targets inside Russia. 

During an interview on the sidelines of  NATO summit in Romania, Rinkevics stated "[w]e should allow Ukrainians to use weapons to target missile sites or air fields from where those operations are being launched." Allies "should not fear" escalation from Moscow, he added. 

While the White House has not publicly told Kiev that it cannot hit Russian territory, in May, President Joe Biden said, "we're not going to send to Ukraine rocket systems that strike into Russia."

However, the Biden administration has explicitly authorized attacks on the Crimean Peninsula, Ukrainian territory that was annexed by Russia in 2014. The Kremlin reacted sharply to a series of attacks in Crimea, including by destroying large swaths of Ukraine's power grid.
