CROWDS led by Hamas leader Ismail Haniyeh chanted "death to Israel" before the funeral of Iran's late president Ebrahim Raisi this morning.
Tehran residents were earlier urged by officials to attend the funeral of "the martyr of service", where Iran's Supreme Leader Ayatollah Ali Khamenei led prayers over coffins.
A prominent role in the event, following Raisi's death in a helicopter crash, was handed to Palestine Hamas leader Haniyeh.
Iran, under Raisi's leadership, has armed the savage militant group throughout its ongoing bloody war with Israel in the Gaza Strip.
Haniyeh today told Iranians gathered ahead of the late president's funeral of when he first met Raisi in Tehran.

He said: "I come in the name of the Palestinian people, in the name of the resistance factions of Gaza … to express our condolences."
Recounting Raisi's words, he added that the Muslim world "must fulfil their obligations to the Palestinians to liberate their land".
He added: "I say once again... we are sure that the Islamic Republic of Iran will continue its support for the Palestinian people," then telling the crowd to chant "death to Israel".
Tens of thousands of black-clad Iranians filled the streets of Tehran this morning to join the funeral processions of Raisi - and seven members of his entourage - who died in a helicopter crash on Sunday.
Mourners were seen clutching portraits of "The Butcher" Raisi in the centre of the city, in and near the University of Tehran, where Iran's Supreme Leader Ayatollah Ali Khamenei led prayers.
Khamenei said: "Oh Allah, we didn’t see anything but good from him," in what is the standard prayer for the dead in Arabic.
Iran's acting president Mohammad Mokhber stood nearby, sobbing.
The caskets of the dead, including Raisi and Foreign Minister Hossein Amirabdollahian, were draped in Iranian flags and pictures of their faces and carried from the university to chants of "death to America".
Top leaders of Iran’s paramilitary Revolutionary Guard attended the funeral, as well as Hamas leader Haniyeh and the deputy leader of Lebanese militant group Hezbollah, Naim Qassem.
Huge banners were strung up in the capital hailing the late president as "the martyr of service" and bidding "farewell to the servant of the disadvantaged".

Tehran residents earlier received phone messages urging them to "attend the funeral of the martyr of service".
There had been celebrations among Iranians after the death of Raisi, who is thought to have been responsible for thousands of deaths under Iran's brutal regime.
From the university, the coffins of those who died in Monday's crash will be driven to the huge Enghelab Square in the city centre and then to Azadi Square, state media said.
Pakistan's Prime Minister Shehbaz Sharif and a delegation from the Taliban of Afghanistan - including its Foreign Minister Amir Khan Mutaqqi - were expected to join processions in Tehran today.
Raisi's helicopter crashed on a fog-shrouded mountainside in northern Iran as the group travelled home after attending the inauguration of a dam project on Iran's border with Azerbaijan.
Search and rescue personnel, aided by Turkey, Russia and the European Union, worked overnight in blizzard conditions to try and locate the missing helicopter and president.
State television announced Raisi's death early on Monday.
The former president, 63, was widely expected to succeed 85-year-old Khamenei as supreme leader.
Funeral rites for Raisi and his entourage began yesterday with processions through Tabriz, where the group had been headed before their helicopter crashed, and the religious city of Qom.
The bodies will be taken from Tehran to Raisi's home city Mashhad, where he will be buried tomorrow evening at the Imam Reza shrine.
Khamenei on Monday declared five days of national mourning and assigned vice president Mohammad Mokhber, 68, as interim president.
An election for Raisi's successor will be held on June 28.
Messages of condolences flooded in from global allies including China and Russia following Raisi's death, as well as from Nato.
The Syrian government and Hamas and Hezbollah praised Raisi and also sent their condolences.
Prosecutors in Iran this week warned residents over showing signs of celebrating the brutal late president's death, as a heavy security force presence was seen on the streets of Tehran.
