The Ukrainian military says three of its soldiers have been killed and 14 wounded in fighting in the country’s east.
Military spokesman Andriy Lysenko said on June 18 that the casualties occurred during the previous 24 hours.
"Clashes aren't getting any less frequent and in certain parts they are turning into full-scale military operations," he added.
Fighting between Ukrainian government forces and rebels has killed more than 6,400 people in eastern Ukraine since April 2014.
In recent weeks, the sides have accused each other of increasing attacks despite a cease-fire agreement signed in Minsk in February.
