Luhansk governor Yurii Harbuz said on Facebook, Censor.NET reports.
"The campaign launched by individual people's deputies of Ukraine and former volunteer fighters of Donbas and Aidar Battalions poses a threat to the energy security of the country. The protesters are blocking empty cars used to transport coal to the government-controlled territory. If the supply of fuel is not resumed, the power plants in central and western Ukraine will run out of energy," Harbuz said.
He added the organizers of the campaign have been officially invited to be observers at all freight train checkpoints.
On Jan. 25, anti-terrorist operation (ATO) veterans blocked the Luhansk-Popasna haul, launching a trade blockade of the occupied Donbas areas. The movement of 12 trains with a total of 700 cars has been barred.
In late December 2016, ATO veterans announced the beginning of an economic blockade of the so-called "Donetsk and Luhansk People's Republics." Yurii Zolkin, the head of the Stanytsia Luhanska State District Administration, supported the blockade of the occupied areas, with a reservation that the ban should apply only to dual use goods.
