Hamas leader Ismail Haniyeh was assassinated in Tehran, Iran's paramilitary Revolutionary Guard said early Wednesday, and Hamas blamed Israel for the attack, the AP reports. Israel has vowed to kill Haniyeh and other leaders of Hamas over the group's Oct. 7 attack on Israel that killed 1,200 people and saw some 250 others taken hostage. An Israeli military spokesman did not immediately respond to a request for comment. Israel often doesn't when it comes to assassinations carried out by their Mossad intelligence agency. Hamas said Haniyeh was killed "in a Zionist airstrike on his residence in Tehran after he participated in the inauguration of Iran's new president." Iran gave no details on how Haniyeh was killed, and the Guard said the attack was under investigation.
"Hamas declares to the great Palestinian people and the people of the Arab and Islamic nations and all the free people of the world, brother leader Ismail Ismail Haniyeh a martyr," the terse statement said. In another statement, the group quoted Haniyeh as saying that the Palestinian cause has "costs" and "we are ready for these costs: martyrdom for the sake of Palestine, and for the sake of God Almighty, and for the sake of the dignity of this nation." Haniyeh left the Gaza Strip in 2019 and had lived in exile in Qatar. The top Hamas leader in Gaza is Yehya Sinwar, who masterminded the Oct. 7 attack. (Israel just carried out a rare strike on Beirut, which it said killed a top Hezbollah military commander.)
