Well it is starting to look like there was no airstrike (Iran media claimed)or pics would be posted by now by citizens it looks like ambush or anti-tank missiles were used to take him out which causes very little damage. This puts Iran in a weird situation if the assassination was due to aircraft, drone or air to ground missiles coming from outside Iran's border Iran would have the right for a military retaliation but if it was done by agents already inside Iran, Iran retaliating militarily would be an escalation and Israel could respond heavily. Israel knew what it did by killing IRGC Generals in their consulate could be considered an act of war which is why they didn't do much when Iran launched missiles at Israel. Bibi may be hoping Iran does retaliate militarily to finally settle this once an for all.
