This seems likely based on the casualty number being reported. Also, Israel is claiming many intercepts so not sure how accurate it is to stay most are getting through.

I'm greatly skeptical that nobody else has been killed, and that damage is minimal.
It might be that Iran doesn't want to cause any real damage (as then Israel would destroy its oil industry and nuclear sites in retaliation) — it only wants to save face. For that, a media picture of "hundreds of missiles falling on Israel" would perfectly suffice — they can sell it domestically. Just bomb some bushes and deserts and call it a day.
