US and other diplomats joined a rally in Hungary against a planned statue honouring a pro-Nazi minister who fomented anti-Semitism in the 1930s.
The diplomats were with several hundred Hungarians at a candle-lit protest in Szekesfehervar, southwest of Budapest.
The town's mayor says a private foundation is entitled to honour Balint Homan with a life-size bronze statue.
The US government's special envoy for combating anti-Semitism, Ira Forman, said "we're shocked by it".
Hungary's Jewish community has urged the right-wing Fidesz government of Viktor Orban to prevent the statue going up.
