"We plan to restrict the movement of goods and people through the line of contact. We have identified seven entrance and exit roads in the area," Lysenko said at a briefing.

Donetsk People's Republic (DPR) transportation minister Semyon Kuzmenko said earlier that transport links in the self-proclaimed republic were running as expected.
Both Kiev and the self-proclaimed republics in the southeast of Ukraine have repeatedly accused each other of violating a September ceasefire agreement brokered by Russia and the Organization for Security and Co-operation in Europe (OSCE).
