Pressure grows on Biden admin to allow Ukraine to use US weapons to hit Russia: 'rather unfortunate'

Russia has reportedly increased its fortifications along the border, from which its forces may strike major Ukrainian targets, such as the city of Kharkiv, while Ukraine must show restraint.

"I don't have the answer why Russia may heavily shell Kharkiv from Belgorod, but Ukrainians may not strike back," Landsbergis, who will attend an informal meeting of NATO foreign ministers in Prague this week, argued. "At a certain point, Russia can read our inaction as an invitation. And we are already at that point."

Biden administration officials have said throughout the conflict that Ukraine may only use U.S.-provided weapons on targets within Ukrainian territory and airspace and actively discouraged any attacks within Russia, but U.S. Secretary of State Antony Blinken indicated on Wednesday that the U.S. is seriously considering if it would allow Ukraine to use American-provided weapons to strike military targets in Russia, citing the evolving tactical situation, according to The Wall Street Journal.
