Ukraine is edging towards "the point of no return", the UN Assistant Secretary General for Human Rights has warned.
Ivan Simonovic told the BBC the divisions in the country were deepening with each incident and called on all parties to de-escalate the tension in the east.
He told Mark Lowen that the window of opportunity to find a solution with a united Ukraine was closing.
