Sorry I read that in a different report here: https://apnews.com/article/iran-explosions-israel-tehran-00234a06e5128a8aceb406b140297299

Israel’s military said about 200 aircraft were involved in the initial attack on about 100 targets. Two security officials said the country’s Mossad spy agency was also able to position explosive drones inside Iran ahead of time and then activate them to target missile launchers at an Iranian base near Tehran.

Crazy that within just a couple weeks Ukraine and now Israel have successfully smuggled drones into a country. Terrifying new vector of war.
