The US Secretary of State is reportedly backing a plan to allow US missiles donated to Ukraine to be fired into Russia

Anthony Blinken is pushing for strict White House rules to be relaxed following a visit to Kyiv last week in the wake of a new invasion from the northern border, the New York Times reported.

Joe Biden has argued that US weapons used inside Russia would be seen as a major escalation in Moscow. Britain has relaxed its rules in recent weeks.

But the US has come under pressure to adapt its policy, particularly after Russian troops and military equipment gathered openly on the border before launching its latest attack north of Kharkiv on May 10.

Volodymyr Zelensky has been arguing for weeks that the US must change its rules to save Ukraine from another major assault on Kyiv.

“This is part of our defense,” Mr. Zelensky told The New York Times. “How can we protect ourselves from these attacks? This is the only way.”
