It is unknown how many remains are in the mass grave discovered by Ukrainian officials in the recently freed eastern town of Lyman, regional governor Pavlo Kyrylenko stated in a Friday online statement.

Separately, a senior police official was quoted by the Ukrinform news agency as reporting that the burial included 180 dead. Saturday, Ukrainian troops recaptured Lyman in the Donetsk region from Russian hands.

Regularly, Ukrainian authorities have accused Russian troops of committing atrocities in the seized territory, an accusation that Moscow rejects.

After the liberation of the northeastern town of Izium, the bodies of 436 individuals were excavated from a mass grave last month. The majority appeared to have died violent deaths, according to local officials.

Kyrylenko, the governor of Donetsk, stated on Telegram that officials in Lyman had discovered "a mass grave where, according to local information, both soldiers and civilians could be buried." The exact amount has not yet been determined."

He reported the discovery of a second cemetery including 200 graves containing the death of civilians. His words did not make clear how or when they died.
