Ukraine's military says that two of its soldiers were killed amid multiple cease-fire violations by Russia-backed separatists in eastern Ukraine on October 16.
One soldier was killed by gunfire from a separatist-controlled district, while the other died after stepping on an explosive device, the military said in a statement on October 17.
It said both deaths occurred in the Donetsk region.
Separatists forces violated the cease-fire 36 times in the previous 24 hours, and Ukrainian forces returning fire 28 times, it said.
There were no statements from the separatists on cease-fire violations.
Fighting between Kyiv's forces and the Russia-backed separatists who hold parts of the Donetsk and Luhansk regions has killed more than 10,000 people since April 2014.
Several cease-fire deals announced as part of the Minsk accords -- September 2014 and February 2015 pacts aimed at resolving the conflict -- have failed to hold.
The latest cease-fire was agreed on August 22 in a phone call between the leaders of Germany, France, Russia, and Ukraine.
