From the official channel of the Ministry of Defense of the Russian Federation (I use automatic translation from Russian to English):
Fake: The Russian Armed Forces and the People's Militia of the DPR shelled Donetsk. This is reported by Ukrainian telegram channels.
Truth: The capital of the DPR was fired upon by the Armed Forces of Ukraine. We made a map showing that residential buildings and civilian infrastructure of the city were attacked.
A 155-mm gun was fired at Donetsk. In Russia, this caliber is not used, in turn, it is standard for the artillery of NATO countries. According to some reports, Donetsk was attacked from American M777 howitzers. According to other sources, they fired from French CAESAR self-propelled guns.
UNIAN claims that Donetsk was fired upon by the People's Militia, referring to blogger Anatoly Dremov. But this is a fake account with 4 thousand subscribers. Dremov's real account has 46 thousand subscribers.
A video appeared on social networks in which a voiceover claims that "I hear a shot - I hear an arrival" and concludes that they are shooting from the city itself. But only "arrivals" are heard on the video - the author of the video misleads the audience.

And another news from the official channel of the Ministry of Defense of the Russian Federation:
Ukraine's defense in Svyatogorsk collapsed, allied forces of the Russian Federation and the DNR complete the "cleansing" of the city
Abandoned by their commanders, the remnants of the 95th Assault Brigade of the Armed Forces of Ukraine and the 81st Separate Airborne Brigade of the Armed Forces of Ukraine abandoned military equipment along with weapons and scattered along the coast. Up to 80 Ukrainian fighters swam across the river. Allied forces deliberately did not open fire on them.
