Some pro-Russian Ukrainians, in occupied territories, have taken their neighbors' children to Russia in order to get financial benefits, using lies to convince them. If they apply for adoption papers, the Russian system will not let their parents get them back.

The article calls this "deportation", but I don't think that term fits the example that it presents. Neither, I think, does "kidnaping." Those terms do properly apply to many Ukrainian children, who were forced to go to Russia by the Putin forces.
