Four Ukrainian servicemen were wounded in the anti-terrorist operation zone in Donbas over the past 24 hours, the presidential administration's spokesman for the operation Andriy Lysenko said.

"There are no fatalities among our soldiers as a result of the hostilities, [but] four soldiers were injured," Lysenko said in a briefing conference in Kyiv on Friday.

The most troubled situation remains in the Donetsk area, [with] cases of shelling recorded there and some shootouts took place, he said.
