Takhti was found dead in his hotel room on January 7, 1968. The Iranian government officially proclaimed his death a suicide. However, some claim that he was murdered because of his political activities against the Pahlavi regime, accusing SAVAK, the Iranian intelligence agency at that time. Because he was a national hero, his funeral drew hundreds of thousands of mourners after being organized by Hossein Towfigh, editor in chief of the (now defunct) Towfigh magazine.
