Haniyeh was laid to rest in a cemetery in the city of Lusail after a funeral ceremony at the Iman Mohamed Ibn Abd Al-Wahhab Mosque in Qatar’s capital Doha.

His coffin, draped in the Palestinian flag, was carried in a procession past hundreds of people along with the casket of his bodyguard, who was killed in the same attack in Tehran on Wednesday.

Mourners at the ceremony included Khaled Meshaal, who is tipped to be the new Hamas leader. Other senior Hamas officials and Qatar’s Emir Sheikh Tamim bin Hamad al-Thani also attended.

Senior Hamas official Sami Abu Zuhri told Reuters by phone: “Our message to the occupation [Israel] today is that you are sinking deep in the mud and your end is getting closer than ever. The blood of Haniyeh will change all equations.”

Khaled Suleiman, who was among the mourners at the mosque, told Reuters: “Today we came … to affirm that the resistance will not end with the martyrdom of the leader, and behind the leader comes a new leader.”

“God willing, all of us will continue and all of us are on the way to the liberation of Al-Aqsa mosque [in Jerusalem], Palestine and Gaza, God willing.”

World reacts to air strikes killing Hamas leader in Iran and Hezbollah commander in Beirut

Haniyeh was killed by a missile that hit him directly in a state guest house in Tehran where he was staying, senior Hamas official Khalil Al-Hayya said in Tehran.

The strike was one of several recent hits that have killed senior figures in Hamas or the Lebanese movement Hezbollah in a conflict that is now stretching from Gaza to the Red Sea and the Lebanon-Israel border and beyond.

In the United States, US President Joe Biden said Haniyeh’s killing was not helpful to international efforts to secure a ceasefire in the war in Gaza.

“It doesn’t help,” Biden told reporters on Thursday, when asked if the action ruined the chances of a truce.

Qatar has been leading the peace effort along with Egypt and the United States, Israel’s main ally.

Haniyeh was the face of Hamas’ international diplomacy as an Israeli offensive destroyed Gaza.

He was seen by many diplomats as a pragmatist compared to the more hardline members of the Iran-backed group inside Gaza, although some Israeli commentators have said he was considered by some on the Israeli side as an obstacle to a deal.

Three of his sons were killed in an Israeli air strike in the besieged enclave in April along with four of his grandchildren, Hamas said.

For Palestinian supporters, the Hamas leadership are fighters for liberation from Israeli occupation, keeping their cause alive when international diplomacy has failed them.

To Israelis and Western states, the Iran-backed Hamas, which has directed suicide bombings in Israel and fought frequent wars against it, is a terrorist group bent on Israel’s destruction.

Appointed to the Hamas top job in 2017, Haniyeh moved between Turkey and Doha, escaping the travel curbs of the blockaded Gaza Strip.

In May, the International Criminal Court prosecutor’s office requested arrest warrants for three Hamas leaders, including Haniyeh, as well as Israeli Prime Minister Benjamin Netanyahu for alleged war crimes. Israel and Palestinian leaders have dismissed the allegations.

While Israel has not said it carried out Haniyeh’s killing, it has announced that an air strike it mounted last month assassinated Hamas military leader Mohammed Deif in Gaza. Hamas has not confirmed or denied the death of Deif.

Hezbollah said that its senior military commander Fuad Shukr had been killed in an Israeli strike on a building in Beirut on Tuesday and it vowed a “definite” response to his killing.
