the only camps in hungatian territory were run by russian collaborationists (communists) after the war. most likely same with romania. not sure what romania did to jews, in hungary they had to do mandatory military labor or go to a concentration camp that was run by germans. hungary only had ghettos, those are very different from a camp, also they had nothing like that for anyone else, only exception is some gypsies, for them it was territory dependent, in some places they did nothing with them in someplaces they were treated the same as jews.
