Read today that the Uke Stasi ( SBU) has arrested 50 Ukrainian Orthodox priests that follow the Russian patriarch, as subversive agents, and a purge of monasteries is underway to find any evidence of Russian liturgy or materials in Russian. A priest recently released in a prisoner exchange has spoken out about the treatment of Ukrainian political prisoners, mistreated because it is not expected they will ever be released.
Maybe this is the report you saw?
I mentioned before, when countries get invaded, their governments can get a little intolerant of opposition nonsense.
In our own Revolutionary War, we tared & feathered British Loyalists and seized their property to help pay for the Revolution.
Ukrainians claim pro-Russian priests are nothing but Russian agents, true or not, who knows?
If Russians care about their Ukrainian priest/agents, they can free them in a peace deal to pull Russian troops out of Ukraine.
Why is that not a good deal?
