The United States has expanded its agreement with Ukraine to allow strikes over the border inside Russian territory wherever Russian forces are engaging in cross-border attacks into Ukraine. This agreement is not limited to the Kharkiv region as previously determined. National Security Adviser confirmed that the agreement extends to anywhere Russian forces are attempting to invade Ukrainian territory from the Russian side.
The Pentagon spokesperson stated that the US has agreed to permit Ukraine to fire US-provided weapons into Russia across the border where Russian forces are attempting to take Ukrainian territory. This marks a significant shift from the previous limited nature of the agreement, which only allowed limited strikes inside Russia primarily in the Kharkiv region.
