Ukrainian President Volodymyr Zelenskyy can now use U.S.-built long range missiles to strike deep into Russia. The Biden administration gave him permission as North Korean troops come to Russia’s aid and Donald Trump prepares to take over the presidency.

The Biden administration gave Ukraine permission to use the long-range guided missile system inside Russian territory, reversing previous restrictions.

A Russian lawmaker calls President Biden's decision to let Ukraine fire U.S. missiles deep into Russia a "very big step toward the beginning" of a third world war.
