Hamas leader Ismail Haniyeh was assassinated in the early hours of the morning in Iran, the Palestinian militant 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, and said it was investigating.
There was no immediate comment from Israeli authorities.
The White House did not immediately respond to a request for comment on Haniyeh.
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.
