The head of the radical Palestinian movement Hamas, Ismail Haniyeh, was killed in a planned operation.
The politician was killed not by an Israeli missile, but by the activation of explosives planted in his residence.
This information was reported by The New York Times (NYT), citing unnamed Middle Eastern officials.
It was not a missile or a guided bomb that killed Haniyeh, the newspaper claims.
Explosives were planted in the Tehran home of the Hamas leader, believed to have been installed two months before the assassination.
The bomb was detonated remotely when information was confirmed that Haniyeh was at her residence.
The NYT notes that the head of the Hamas politburo was killed as a result of a carefully planned operation.
It lasted for at least several months and began with surveillance of a politician's residence in the Iranian capital.
Then unknown persons planted a bomb in the house and began to wait for the moment when it could be detonated.
