President Joe Biden’s administration and the U.S. Department of Defense are investigating whether U.S. equipment was used during a cross-border raid into Russia earlier this week.
On Monday, a pair of paramilitary groups crossed the border from Ukraine into Russia’s western Belgorod region to sow chaos inside Russia’s borders. The paramilitary fighters identified themselves as members of Liberty of Russia Legion and the Russian Volunteer Corps, two groups of self-described Russian nationals who say they oppose the current government under Russian President Vladimir Putin. Russian officials have claimed to have repelled the apparent rebel groups.
