The Freedom of Russia Legion comprises defectors from the Russian army and other volunteers.
The anti-Putin group launched two cross-border raids into the Belgorod region in May and June.
Its commander told The Observer it's planning more attacks, bolstered by the dissolution of Wagner.
"There will be a further surprise in the next month or so," the Freedom of Russia Legion's spokesperson and commander, Caesar, told the newspaper.
The Freedom of Russia Legion is based in Ukraine and comprises a few hundred soldiers, who are defectors from the Russian army and other volunteers fighting against their homeland.
