Haniyeh was in Tehran to attend the inauguration ceremony of the new Iranian President Masoud Pezeshkian on Tuesday (July 30).

Iranian officials have condemned the attack, labeling it an act of terrorism and vowing to bring those responsible to justice. They have launched an immediate investigation to uncover the perpetrators behind the incident.

Hamas, in an official statement, expressed deep sorrow over the loss of Haniyeh, who they described as a “martyr for the Palestinian cause.” The organization vowed retaliation, further heightening concerns of an escalation in violence.

As the investigation continues, the world watches closely, bracing for the possible repercussions of this high-profile killing.
