Second time I'm hearing this being mentioned in a Persian-language "YouTube" video, but why am I not finding the slightest confirmation in French online media?
Performed several searches using various word combinations on a search engine, as well as a query at the website of the French daily Libération.

The French foreign ministry stating that sardar Qa'ani was present in Mali and that Iran had a role in recent anti-imperialist coups of west Africa isn't reported anywhere in French media (nor by other sources except for a few Iranian social media users).
Now I'm not myself excluding the possibility, nay probability that Iran has been extending some form of assistance to the movements in question, but this item here appears to be fake news. Unless someone can find a local source reporting it, in which case I'd be grateful if they could share it here. Friends in Iran would gain in verifying such rumors or citing their primary source.
