Ukraine can use US weapons for limited strikes in Russia, Joe Biden says

From the article:

The policy shift, disclosed by U.S. officials on the condition of anonymity to discuss the president’s decision, authorizes Ukrainian commanders to “hit back against Russian forces that are attacking them or preparing to attack them” in and around Kharkiv, near the border in northeast Ukraine. President Volodymyr Zelensky and other top officials in his government have campaigned for the shift with increasing urgency as Russia has pressed its assault there, emboldened by the Kremlin’s knowledge of Washington’s red lines, officials in Kyiv say.

…

A growing number of the United States’ European allies in recent days also had urged the administration to lift its opposition, signaling an intent to allow their own weapons to be used against military targets on Russian soil. Although Ukraine has used some European arms as well as their own to fight back, Washington’s say-so has been the most important because of the quantity and the quality of its equipment.

The shift allows Ukraine to use U.S.-provided artillery and rocket launchers to hit Russian troops and equipment just across the border from Kharkiv and to strike missiles headed toward Ukrainian territory, U.S. officials said. They emphasized that the Biden administration’s policy barring longer-range strikes inside Russia “has not changed.”

Biden signed off on the change several days ago, and the policy went info effect Thursday.
