Russia on Tuesday said it quelled an attack in Belgorod, just over the Ukrainian border some 50 miles north of Kharkiv, killing dozens of attackers in a roughly 24-hour fight.
Moscow claimed the saboteurs were Ukrainian, though Kyiv has said it had nothing to do with the assault, and two separate anti-Vladimir Putin groups have claimed credit for the attack, according to Reuters.
The Russian Volunteer Corps (RVC) and Freedom of Russia Legion have both said they were responsible for the attack that reportedly saw some 70 attackers killed in a raid that began Monday.
Fox News Digital has not verified who was behind the attack or whether Kyiv was involved in any way.
The Freedom of Russia Legion was formed in 2022 following Russia’s invasion of Ukraine and claims to cooperate with the Ukrainian armed forces and operates under Ukrainian command, similar to groups fighting against Russia from nations like Belarus.
The RVC is a group that was also formed last year and is made up of Russian nationals who have been fighting in and for Ukraine against Moscow. It was reportedly responsible for a March attack in Belgorod.
The groups are apparently not affiliated.
The Russian Belgorod region is a vital hub for Moscow’s war effort in Ukraine, housing fuel and ammunitions depots. It was listed by Putin last year when he ordered certain areas increase their state of readiness and defenses.
Russian defense ministry spokesman Igor Konashenkov claimed local Russian forces and air strikes worked to repel the attackers.
"The remnants of the nationalists were driven back to the territory of Ukraine, where they continued to be hit by fire until they were completely eliminated," he said.
Russian officials have not said how many Russians were killed in the assault.
A dozen Russian civilians were injured in the attack.
