Iran has officially claimed that the assassination of Hamas political leader Ismail Haniyeh in Tehran earlier this week was carried out by a "short-range projectile" and a "severe explosion" outside the guest house where he was staying. This contradicts previous information reported by CNN, which stated that Haniyeh was killed by an explosive device secretly planted inside the guest house.

The death of Ismail Haniyeh has further heightened tensions in the region, fueling fears that the conflict between Israel and Hamas could escalate into a full-scale war in the Middle East. Both Iran and Hamas have pointed fingers at Israel, accusing them of carrying out the assassination. However, Israel has neither confirmed nor denied any involvement.

Iran, in response to the killing, has issued a warning that "blood vengeance" for Haniyeh's death is certain. The Islamic Revolutionary Guard Corps (IRGC) released a statement claiming that their investigation and research showed that a short-range projectile, armed with a warhead weighing approximately seven kilograms, was responsible for the assassination.

On the other hand, CNN's source, who had been briefed on the matter, stated that a bomb had been hidden inside the guest house where Haniyeh frequently stayed, and was remotely detonated. US officials were informed about the operation by Israeli officials after the assassination occurred.

The IRGC alleged that the "Zionist regime," referring to Israel, planned and executed the assassination with support from the American government. Iran vowed that Israel would face severe punishment for their actions, stating that it would be delivered at an appropriate time, place, and manner.

In response to the escalating tensions, Israel's chief spokesperson for the Israel Defense Forces (IDF), Rear Admiral Daniel Hagari, declared that Israel is on "high alert" for both defensive and offensive military actions. The IDF has deployed forces in the air, at sea, and on the ground, preparing for various scenarios, including offensive plans in the immediate future.

CNN has reached out to the Iranian government for comment on the matter, but has yet to receive a response.

As tensions rise in the region, the international community watches closely, hoping for a peaceful resolution to the ongoing conflict between Israel, Hamas, and their allies.
