"The observers should make public the names of those responsible for gross violations of the first two points of the [February] Minsk agreements," Denis Pushilin said as quoted by Donetsk news agency.
The 13-point peace agreement signed by sides to Ukraine conflict in Minsk, Belarus, in February contains a range of steps that both Kiev and Donbass forces need to take to de-escalate a year-long conflict, including a February 15 ceasefire agreement and heavy weaponry withdrawal from the line of contact.
Under the deal, a constitutional reform should be held in the country granting special status to the eastern regions of Donetsk and Lugansk.
The authorities of the self-proclaimed people's republics of Donetsk and Lugansk have repeatedly accused Kiev of violating the key provisions of February Minsk peace accord.
