Ukraine's military and the pro-Russian separatists have accused one another of violating a truce at the airport in rebel-held Donetsk in eastern Ukraine just hours after it was agreed to.
The Ukrainian military said on December 1 that it had agreed with Russian military officials on a temporary cease-fire at the airport in Donetsk.
That cease-fire was due to begin on December 2.
But Ukrainian military spokesman Andriy Lysenko said on December 3 the rebels resumed rocket strikes after the truce negotiations.
But officials from the self-proclaimed Donetsk People's Republic said Ukrainian forces were guilty of "multiple violations" of the agreement.
Meanwhile, former Ukrainian President Leonid Kuchma said fresh talks with Russian, pro-Russian separatist, and Organization for Security and Cooperation in Europe envoys could begin next week.
Kuchma is Kyiv's representative at the so-called contact group.
