Biden changes stance to allow Ukraine to fire US-supplied weapons into Russia

US official says policy change relates to counter-fire purposes' and prohibits long-range attacks inside of Russia

Joe Biden has allowed Ukraine to use some US-made weapons over one part of the Russian border, to allow Kyiv's forces to defend against an offensive aimed at the city of Kharkiv, relaxing an important constraint on Ukraine's able to defend itself.

The president recently directed his team to ensure that Ukraine is able to use US-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," a US official said.
