Basically there were protests (mainly by business-owners) about currency instability (we’re talking thousands in big cities). Nothing drastic happened. Then the next day violent thugs started assaulting police stations with Molotov cocktails (and, in one case, a flamethrower), it’s probably quite clear to most in Iran that those are paid agitators/Mosad assets. It’s not the first time.

When it comes to current events in Iran, I recommend to look for prof. Mohammad Marandi’s interviews on youtube; he’s always there on some progressive/anti-imperialist channel. Here’s one I found where he discusses those protests: https://www.youtube.com/watch?v=mqsy4f0OE8M
