"This was done to draw attention to inhuman tortures in the basements of the MGB [the so-called 'ministry of state security']. Inhuman treatment and tying electric wires to limbs in the 'people's' republics have become the norm. The people of Donbas should go to a rally in protest against torture, or the fascist republic will be left without communications," the ultimatum says.

The incident occurred in Donetsk's Proletarsky district on the morning of Sunday, October 27. The "DPR" de-facto authorities said that mobile communications services might worsen.

The "DPR" built its telecoms network on the basis of the equipment seized from Ukrainian mobile operators, including Kyivstar.
