Rumor News: Supposedly Iran has executed Ismail Qaani, the commander of the Quds, the operator units that was once Soleimani's. At least according to rumors and in the spanish-speaking media outlets.
So perhaps those rumors by politicians that the Ayatollah had unknowingly placed a spy as head of the covert ops organization are probably true if this event is true itself. Allegedly he had the luck to be in the top-tier meetings that were bombed but left earlier in both instances, both a year ago when the IRGC leaders got bombed at the "safe" location (rumored to be that one white high-rise that got demolished) and currently when the negotiation table meeting happened at the 'tollah's residential compound. Also these claims mention he met Nasrallah a day before the guy got bombed, and Qaani's role does give him the possibility to be in that position.
Imagine that, Soleimani getting bombed and his successor being a rival Mossad agent, a nightmare scenario for the IRGC.
