Hello!
It seems that Russian Ministry of Defence has admitted 4 Russian planes lost. One of them is Tu-22 and three(?) Su-25.
The Tu-22 (or Tu-26M3-R) was reconnaissance plane from 929 GLITs (some kind of testing unit). One of the crew died. This posting at VIF2-forum gives even the tactical number "36" for the plane:
