TEHRAN: The funeral prayer for Hamas political leader Ismail Haniyeh, who was assasinated on Wednesday, was offered today (Thursday) by Iran's Supreme Leader Ayatollah Ali Khamenei at the University of Tehran in Iran.

The services began with an address from Iran’s parliament speaker Mohammad Bagher Ghalibaf.

"Martyr Ismail Haniyeh was the voice of the Palestinian people all over the world," Ghalibaf said. "He was not only a leader. He was the wise man."

Ghalibaf added that Haniyeh's assassination, in Tehran, on Wednesday, would not go unanswered.

"Our reply will be there. At the right time and the right place. It is difficult for us to have our guest being targeted and assassinated on our soil," he said.

Following funeral prayer of slain Hamas leader Ismail Haniyeh, the procession is set to head towards Azadi (Freedom) Square, according to Al Jazeera.

Haniyeh's body will then be flown to Doha for burial.

Khalil al-Hayya, the deputy head of Hamas in the Gaza Strip, addressed the Haniyeh's funeral service in Tehran.

"The nation today is carrying his coffin, and the nation today is raising the flag of jihad and resistance towards the goal of liberating Palestine and Jerusalem," al-Hayya said.

"With the faith of our country, and the Palestinian soul, we are sure that the assassination of Ismail Haniyeh will bring anger towards this Zionist entity from the entire people of the world."
