With the Ukrainian army struggling to contain the grab for power by the self-proclaimed Donetsk People's Republic (DPR) in the Donetsk Oblast, armed pro-Ukrainian militias have been quietly taking matters into their own hands.

They were cautious about revealing their location as their last HQ was discovered and attacked by pro-Russia forces, forcing them to find an alternative.
