"After three months' work and numerous approvals, we have listed absolutely all types of violation, including the ones that are not connected with war," Marchuk said.
"These are, for example, the presence of unauthorized persons in the zone of disengagement and obstacles to OSCE monitors' work when they are denied access to a facility where and when they want to," he explained.
"The parties' responsibilities and instructions that need to be followed in case violations have clearly been stipulated," Marchuk said.
Marchuk said a 13-day schedule had been developed as part of the disengagement agreement. "I think that the disengagement should start this week, for sure," he said.
