"The Donetsk People's Republic continues its withdrawal of heavy weapons from the contact line outlined in the Minsk agreements from September 19 last year," Basurin told reporters.
Basurin added that the situation at the contact line is gradually stabilizing, and the militia "strictly observes the ceasefire and does not respond to sporadic provocations from Ukrainian troops."
The pullout of Kiev's and independence forces' heavy weaponry from the contact line into a newly-formed 50-140 kilometer (31-85 miles) security zone was given a two-week deadline starting February 15.
Basurin reiterated DPR's adherence to the latest Minsk agreement and invited OSCE observers to monitor the continued withdrawal of heavy weaponry.
Four days after the ceasefire came into effect, the OSCE noted it was broadly observed "despite some incidents" in Donetsk, Luhansk and the neighboring railway hub of Debaltsevo.
The large-scale military campaign between government forces and independence fighters in southeast Ukraine has claimed nearly 5,600 civilians, according to the United Nations, since it was launched in mid-April 2014.
