A disturbing video has been released by Chechen Muslim rebels associated with ISIS.
The video shows them beating a Muslim woman because they think she's been flirting with a Russian soldier.
The woman, who was covered from head to toe in a Burkha, was tied to a table with a rope and beaten mercilessly. They took it further by humiliating her and filmed the entire assault.
The Chechen rebels are currently at war with Russia so it was a huge blow to them seeing the woman getting close to the Russian soldier.
