It looks like they did a true tit-for-tat, blowing up a target with a missile (or a planted explosive). Reporting is early, so it's hard to tell, just like with the Ismael Haniyeh situation.
The photo is from Tel Aviv (and off Facebook, lol), it seems to show the response. Haven't seen any photos of the explosion itself yet, but I'm sure those will be coming out shortly.
It could have also been some other group, but that seems unlikely.
I've been waiting for Iran to actually do something for what feels like forever!
I heard that Netanyahu died while shitting his doodoo ass on the toilet with his pants at his ankles and his secrwt service detachment knocked on the door when hey saw the missiles flying in and they knocked on the door and said 'mr netamyahu sir it's happening time vo to to the bunker' but he stood up too fast and his legs had gone numb from sitting so he tripped on his pants and fel face first and cracked his face open amd died right there on the spot
