Hamas chief Ismail Haniyeh assassinated in Iran, group says in statement

Hamas leader Ismail Haniyeh was assassinated in the early hours of the morning in Iran, the Palestinian group Hamas said on Wednesday, describing the strike as a "severe escalation" that would not achieve its goals.

Iran's Revolutionary Guards confirmed the death of Haniyeh, hours after he attended a swearing in ceremony for the country's new president Masoud Pezeshkian, and said it was investigating.

"Early this morning, the residence of Ismail Haniyeh in Tehran was struck, resulting in his and one of his body guards' martyrdom. The cause is under investigation and will be announced soon," the Revolutionary Guards said.

The news, which came less than 24 hours after Israel claimed to have killed the Hezbollah commander it said was behind a deadly strike in the Israeli-occupied Golan Heights, appears to set back chances of any imminent ceasefire agreement in Gaza.

"This assassination by the Israeli occupation of Brother Haniyeh is a grave escalation that aims to break the will of Hamas," senior Hamas official Sami Abu Zuhri told Reuters.

He said Hamas would continue the path it was following, adding: "We are confident of victory."

There was no immediate comment from Israeli authorities.

Haniyeh was the tough-talking face of the Palestinian group's international diplomacy as war raged back in Gaza, where three of his sons were killed in an Israeli airstrike.

But despite the rhetoric, he was seen by many diplomats as a moderate compared to the more hardline members of the group inside Gaza.

Appointed to the Hamas top job in 2017, Haniyeh moved between Turkey and Qatar's capital Doha, escaping the travel curbs of the blockaded Gaza Strip and enabling him to act as a negotiator in ceasefire talks or to talk to Hamas' ally Iran.

"All the agreements of normalisation that you (Arab states) signed with (Israel) will not end this conflict," Haniyeh declared on Qatar-based Al Jazeera television shortly after Hamas fighters launched the Oct. 7 raid.

Israel's response to the strike has been a military campaign that has killed more than 35,000 people inside Gaza so far, according to health authorities in the territory.

Sons killed in airstrike

Three of Haniyeh's sons - Hazem, Amir and Mohammad - were killed on April 10 when an Israeli air strike struck the car they were driving, Hamas said. Haniyeh also lost four of his grandchildren, three girls and a boy, in the attack, Hamas said.
