I dunno. Trying to extract some info from TASS. If somewhere a casualty report on behalf of the Russian govt. would appear I guess TASS would be the first one.
I only found this:
>As many as 1,612 targets have been hit since the start of the operation, including 62 command posts and communications centers, 39 S-300, Buk M-1 and Osa missile systems and 52 radar stations
>49 aircraft were destroyed on the ground and another 13 in the air. A total of 606 tanks and other armored combat vehicles, 67 multiple rocket launchers, 227 field artillery pieces and mortars, 405 military motor vehicles and 53 unmanned aerial vehicles were also destroyed.

Their source is:

Which usually means Reuters, but not sure that it is now.
