President Biden has given the green light for Ukraine to use American-made weapons to strike inside Russia, marking a major reversal of policy, Fox News has confirmed. 

A senior U.S. official confirmed that President Biden has signed off on the Ukrainians’ use of U.S. long-range weapons near the city of Kharkiv to protect the second-largest city from ongoing Russian assault. 

The official described the reversal as a "limited" policy shift related to Kharkiv rather than a broad shift in policy that would open up use of U.S. weapons inside Russia.

PRESSURE GROWS ON BIDEN ADMIN TO ALLOW UKRAINE TO USE US WEAPONS TO HIT RUSSIA

"The president recently directed his team to ensure that Ukraine is able to use U.S.-supplied weapons for counter-fire purposes in the Kharkiv region, so Ukraine can hit back against Russian forces that are attacking them or preparing to attack them," the U.S. official said. "Our policy with respect to prohibiting the use of ATACMS or long-range strikes inside of Russia has not changed."
