Actions in which Jaakov Meidad was involved
Eichmann in Buenos Aires (May 11, 1960)
Herbert Sugar in Montevideo (February 23, 1965)
In 1965 he was supposed to find and liquidate Cukurs . For this purpose, Meidad founded front companies in Vienna, with these business papers Meidad alias "Anton Künzle" was able to lure Cukurs to Uruguay. There, Cukurs should take a stake in a branch of the entrepreneur Künzle. When Cukurs entered an alleged office of the front company in Montevideo in March 1965, the "hangman of Riga"  was beaten in the head by several Israelis; afterwards Cukurs was shot dead. This is attributed to Meidad by other Mossad colleagues as a "national [...] heroic act"  .
