The secretary of Ukraine's National Security and Defense Council Oleksandr Turchynov said he would not allow the blockade of the "DNR" and "LNR" by groups of volunteers.
The decision to block must be taken by the commander-in-chief, he said.
Turchynov said he would not allow impromptu roadblocks in the ATO zone
"It is not going to happen," he told reporters .
On Monday, a number of former and current ATO fighters, affiliated with Donbas and Aydar battalions, announced plans to launch mobile groups and set up roadblocks to prevent illegal trade with the uncontrolled territories of Donbas. The purpose of the blockade is to force "DNR" and "LPR" to release the captives.
Earlier, Turchynov said all traffic of people and commodities across the frontline line in Donbas should be stopped.
