One Ukrainian soldier has been killed and four injured in the country's east, where government forces and pro-Russian separatists continue to trade fire despite a ceasefire.
"Ukraine has lost one serviceman and four more sustained injuries" in the past 24 hours, military spokesman Vladyslav Seleznyov told reporters in the capital Kiev.
The soldier's death brings to 65 the number of troops killed in sporadic clashes along the frontline since the February 12 peace deal was signed, according to the government.
The separatists rarely give accounts of their losses.
Kiev said the latest skirmishes took place near the bombed-out shell of Donetsk airport, which the rebels control, as well as in Shyrokyne, a village near the southeastern port of Mariupol.
Mariupol remains in government hands.
The peace deal calls for the removal of all artillery of a calibre of 100 mm or more.
President Petro Poroshenko confirmed on Monday that both sides had withdrawn most of their heavy weapons, yielding a tense calm along much of the 485-kilometre (300-mile) front line.
Yanukovych fled to Russia, which went on to annex Ukraine's Crimea peninsula.
