Yeah, in sure that drone factory is also making drones used by the houthis against Saudia Arabia. As well as by syrians against israel. As well as being used by Russia against Ukraine. Plus the kurds. And the USA doesn't approve either.

Kurds or Saudi Arabia would be the likely candidates that can get drones into Iran without crossing another countries airspace. I always wonder how Israel got to get Iran to bomb it back in the day. They would have had to cross several hostile countries to even get to iran.
