"In the last day, we lost two Ukrainian soldiers, and another nine were injured as a result of military clashes," Motuzianyk said.

According to him, the Ukrainian soldiers were killed by enemy fire in the "B" sector to the west of the militant-held city of Donetsk.

Motuzianyk also commented on the information spread by Ukrainian volunteers that Ukrainian marines had been killed in the "A" sector, which is the northern area of Luhansk region.

"We've got such preliminary information – it happened at around 00:30 local time today. The enemy launched shelling our positions, which are located outside [the Ukrainian-controlled city of] Mariupol, in particular, these are the villages of Lebedynske and Sopyne. According to early reports, two of our soldiers were killed and three were wounded in that shelling. This information is preliminary, details will be announced tomorrow," he said.

Earlier, local media reported that Russian proxies had shelled the outskirts of Mariupol from 152mm self-propelled artillery systems, having killed a Ukrainian marine.
