"I have some good news. There has been no shooting on the front for a week," Poroshenko said in televised remarks. "This is the first week that the Minsk agreements are being implemented."
Poroshenko added that soldiers were still perishing in the conflict zone by stepping on landmines or in car crashes, but that none had died in battle.
Yesterday, a Ukrainian soldier was killed in the blast of an "unknown explosive device" in the Lugansk area, one of the two eastern regions controlled by pro-Russian rebels.
The Western-brokered ceasefire agreed in February had been punctuated by deadly incidents on an almost daily basis.
But the truce was nonetheless undermined on Wednesday when two civilians were killed and four soldiers wounded in an ambush while taking part in an anti-smuggling operation.
Self-proclaimed separatist authorities announced today that a civilian near the rebel stronghold of Donetsk had been killed by shots fired by the Ukrainian army.
