I was wondering why Kiev would announce this. They usually don’t announce any losses they can deny.
At least one of the SU-25 shootdowns was filmed.

Rebel Twitter reports say one of the SU-25’s shot down was attacking Rebel positions near Shakhtersk, Donetsk ,close to the MH17 crash site, and within the declared “Ceasefire” Zone.
So much for Poroshenko’s “Cease-fire”.
