Yemen is adjacent to Saudi Arabia. Iran's conflict with Saudi Arabia is probably the most salient in all of the Middle East and Northern Africa, more so than the "west vs. Arabia" conflict we default to thinking about. The Houthis (Ansar Allah), named for a dude who died just a few years ago, were trained in Iran, and are an effort to replicate the Iranian Revolution in Arabia.
The Houthis are often thought of as an arm of the IRGC (Iran refers to them as part of their "axis of resistance", along with Hezbollah and Hamas), but they are their own thing, although Iran is believed to be actively assisting them with spotter ships in the Red Sea.
This is just a shotgun blast of additional details. Nobody really knows what Iran's game plan is here.
