As Censor.NET reports with reference to InformNapalm, this is confirmed by video recording with confession of one of the terrorists of a criminal gang in 'DPR.' He told that since September 2014, he had been trained in a training center in 'DPR,' city of Donetsk, and then became a field-engineer instructor. After his instructions, newly arrived volunteers from among the enlisted local population or mercenaries from the Russian Federation went on to an advanced course. This additional coaching was carried out in a terrorists' training camp near Rostov-on-Don.
It is noteworthy that the terrorist was involved in a series of staged stories which were widely replicated at pro-Russian websites and in YouTube. They featured Bondaruk telling how his unit in allegedly combat conditions deactivated mines and tripwires left by the Ukrainian army, and called for humanitarian aid for his soldiers fighting against the «junta».
