President Joe Biden has authorized Ukraine to use U.S.-supplied long range missiles to strike Russia, Reuters reported, citing sources. This marks a U.S. policy shift coming at the tail-end of Biden's time in office. President-elect Donald Trump has vowed to limit U.S. support for Ukraine and end its war with Russia.

The decision is a major change in U.S. policy and comes as Donald Trump, who has promised to limit further support for Ukraine, prepares to take office.

The Biden administration will allow Kyiv “limited” use of the ATACMS long-range missile system to strike enemy positions in Kursk, a significant reversal of U.S. policy.
