The previous arrest warrant issued for Mr. Trump and other officials was rejected in June

Karimi law firm represents according to Aljazeera:

Iran has fielded a "red notice" requesting the Interpol to arrest Donald Trump and 47 other American officials identified as playing a role in the assassination of top general Qassem Soleimani last year; alleged Iranian judiciary spokesman Gholamhossein Esmaili during a press conference on Tuesday.

He further added, “The Islamic Republic of Iran is very seriously following up on pursuing and punishing those who ordered and executed this crime”.

Interpol didn’t grant a previous arrest request by Tehran prosecutor Ali Alqasimehr when he issued an international warrant in June for the arrest of Mr. Trump and other officials at the Pentagon and US central command on “murder and terrorism charges”. 

Rejecting the June request, Interpol said that its constitution forbids it from taking on any "intervention or activities of a political, military, religious or racial character”.
