Two Ukrainian soldiers and a pro-Russian separatist have been reported killed in the country's east.
Army spokesman Andriy Lysenko said on April 8 that two soldiers had been killed and four wounded in the past day.
The rebels said one of their fighters was killed and three were injured.
Both sides accused each other of violating a cease-fire agreed in Minsk in February in an effort to end a conflict that has killed more than 6,000 people since April 2014.
Lysenko said separatists fired mortars and tank rounds at Ukrainian positions on more than 10 separate occasions near the government-held port city of Mariupol and the rebel-controlled provincial capital of Donetsk.
The separatists accused the Ukraine Army of 45 attacks on their positions, including in the town of Spartak and Donetsk.
