Six Ukrainian servicemen were killed aboard two helicopters while they were "carrying out missions" in eastern Ukraine, the military said on Wednesday, reports Reuters.
There was no indication what happened involving two widely-used Mi-8 helicopters on Tuesday, it said.
A military statement said the men were "carrying out missions" in the sector of the Russian-held eastern city of Bakhmut when they died.
The news site Ukrainska Pravda said the incident occurred near Kramatorsk - a large town west of Bakhmut in Donetsk region, theatre of much of the fighting in Russia's 18-month invasion of its neighbour.
It said the two helicopters were "completely destroyed" and the bodies were found at the site.
