The United Nations peacekeeping mission, the deployment if which in Donbas is requested by Ukraine, should help restore Ukraine's sovereignty, rather than freeze the conflict, Ukrainian President Petro Poroshenko has said.

"Deployment of a UN peacekeeping operation should restore justice, rather than freeze the conflict and cement the occupation. And the justice would be: to restore Ukraine's sovereignty over its territory. The justice would be: to make sure that no one can take away Ukraine's freedom," Poroshenko said when addressing the UN Security Council in New York on Wednesday.
