Not to be confused with International Red Aid (MOPR), an organization established by the Comintern in 1922 to coordinate material and moral aid to so-called "class war prisoners" around the world.

The Workers International Relief (WIR) — also known as Internationale Arbeiter-Hilfe (IAH) in German and as Международная рабочая помощь (Mezhdunarodny Rabochy Komitet Pomoshchi Golodayushchim Rossii − Mezhrabpom) in Russian — was an adjunct of the Communist International initially formed to channel relief from international working class organizations and communist parties to famine-stricken Soviet Russia. The organization, based in Berlin, later produced films and coordinated propaganda efforts on behalf of the USSR.
