Tonight, CBS News has learned that President Biden has quietly
given the go ahead for Ukraine to launch limited air
strikes with US weapons inside Russia.
Ukraine may use the weapons on the Russian side of
the border near the besieged Ukrainian city of Harkeev against
concentrations of Russian troops,
artillery, and planes. This is a reversal of the president's
previous ban on such actions,
and it could escalate tensions with the Kremlin.
