According to the Wednesday report, Tehran is now convinced that Haniyeh was killed when someone activated a remot-controlled bomb in the room where he was staying, and not in a direct military operation.
Washington stressed to Tehran that such an action, so long as no Iranian citizens were killed, does not justify a direct military operation against Israel.
The source also told Politico that Iran intends to respond to Haniyeh's elimination in some way appropriate for the actual act, but that a strong attack on Israel is not expected in the near future.
In addition, the source said that the US warned Iran of the dangers in a direct attack on Israel, hinting that the US would support an Israeli response to any significant attack. Israel National News - Arutz Sheva
