Russia-backed rebels in eastern Ukraine accuse Kiev's forces of killing four separatists, while Ukraine announced the death of one soldier.
Eduard Basurin, a senior rebel representative, told AFP news agency on Saturday that four fighters were killed by Ukrainian forces on Friday in the south of the Donetsk region. No civilians were injured, he said.
Dmytro Gutsulyak, press secretary of Ukraine's defence ministry, said at a briefing on Saturday that one of the Ukrainian troops was killed on Friday as rebels carried out nine "provocative shellings" of Ukrainian positions.
At least two other Ukrainian soldiers were also injured in the attacks.
The soldiers killed at least six separatists and injured seven more on Friday.
"The defenders of Ukraine continue to control the enemy on the line of contact, while respecting the conditions of a ceasefire," Pravda quoted the press office of the Ukrainian forces as saying.
The toll in the last 24 hours was the highest since the latest fragile ceasefire entered force in the war-torn region on December 29.
