Hamas leader killed - latest: Ismail Haniyeh assassinated in Iran in major escalation of Middle East crisis
Hamas's political leader Ismail Haniyeh has been killed in Iran in a "treacherous Zionist raid", the group has said. Haniyeh had been leading talks on a new ceasefire and hostage release deal, and his assassination puts negotiations in doubt. Israel has yet to comment on his death.
Though Israel has not claimed responsibility, the killing of the leader of the political wing of Hamas - Ismail Haniyeh - is a major blow to the group.
Haniyeh was the pragmatic face of Hamas. He was less hard-line and militaristic than Yahya Sinwar, who is the head of Hamas inside Gaza and is leading the battle.
Haniyeh was the public face of Hamas's diplomacy in Arab capitals. He was leading efforts to negotiate a ceasefire in Gaza. In recent years he's been based in Qatar, which hosts the political wing of the group, but he has shuttled between Turkey, Lebanon, Iran, and Egypt.
Hamas leader killed: Ismail Haniyeh assassinated in Iran
Aside from the regional implications, within Hamas this will necessitate a change of leadership at the top. But the group is adept at this. Its structure allows for a smooth transition of power.
The assassination of Hamas leaders is not unusual. Hamas founder, Sheikh Ahmed Yassin, was assassinated in 2004. A month later another senior leader, Abdel Aziz al-Rantisi was also killed by Israel. It was only a matter of time before Israel's reach extended to the current leadership of the group.
Within the Palestinian national movement, Haniyeh was a popular figure, even among those who were adamantly opposed to its ideology.
He was born in the refugee camps of Gaza, in al-Shati - or beach camp. He joined the group as a young man and rose through its ranks.
Haniyeh led Hamas's brief foray into politics. The group beat its political rival Fatah in the Palestinian national elections in 2006.
But the international community would not accept the result. A brief civil war in Gaza between Hamas and Fatah followed.
Fatah was kicked out of the strip. Hamas took over. Haniyeh's short-lived term as Palestinian prime minister was over and Hamas and Fatah have been bitter rivals ever since, despite a few attempts at reconciliation.
What is Hezbollah and how powerful is its military?
I last interviewed Haniyeh in 2016, he said then "It is difficult to break the will of the people of Gaza, they can handle the siege."
Asked about building tunnels, he said: "We are preparing to defend the Palestinian people with all our resistance."
Many Gazans blame Hamas for leading them into this devastating war, but they also know Haniyeh's death will put any remote chance of a ceasefire on hold, while the ramifications of this assassination play out.
