The decision by President Biden will allow Ukraine to fire into Russia using US long-range missiles it's had for more than a year.

Joe Biden has sensationally granted Kyiv permission to use “long-range “ missiles to strike targets deep within Russia, despite Vladimir Putin describing such a move as an act of war.The weapons are likely to be used in response to North Korea’s decision to send thousands of troops to Russia in support of President Vladimir Putin’s invasion of Ukraine and comes after months of pressure from Ukrainian President Volodymyr Zelensky He argued the US ban had made it impossible for Ukraine to try to stop Russian attacks on its cities and electrical grids.

Russia has warned that any approval from the Biden administration to use ATACMS missiles would be viewed by the country as an act of escalation.
