Israeli media reports have revealed that the missile which killed Hamas political bureau chief Ismail Haniya in Tehran was launched from within Iran. Channel 12 in Israel stated that "according to the analysis of information from Iran, the missile that killed Haniya (between Tuesday and Wednesday) was launched from inside Iran, and did not come from an aircraft or drone," as claimed by Tehran. Iranian-affiliated media had confirmed that the missile that killed Haniya and his companion at two o'clock in the morning on Wednesday Tehran time came from outside Iran. This analysis mentioned by Channel 12 raises discussions about a "major security breach" within Iran that allowed for the targeting of a prominent Hamas political leader inside Tehran. Hamas and Iran stated that Haniya was assassinated in the early hours of Wednesday morning in Tehran, igniting a wave of threats of retaliation against Israel in a region already ravaged by war in the Gaza Strip and escalating conflict in Lebanon. The Iranian Revolutionary Guard confirmed Haniya's death just hours after he attended the inauguration ceremony of the new president of the country, Masoud Bezhkishan, and stated that an investigation is underway. Despite assumptions that Israel carried out the attack, the Israeli government did not claim responsibility and said it would not comment on the assassination.
