The Iranian acting foreign minister says the country has no option but to retaliate against the Israeli assassination of Ismail Haniyeh in Tehran.

The Iraian president made the remarks in a phone conversation with French President Emanuel Macron.

Iran’s Interim Foreign Minister Ali Bagheri Kani says the martyrdom of Ismail Haniyeh, the political leader of Hamas, has strengthened the resistance front in Palestine and across the region.

The Ain al-Assad airbase of US occupation forces in western Iraq came under rocket attacks twice in less than 12 hours on Monday, resulting in several military casualties.

The assassination of Hamas political bureau chief Ismail Haniyeh in Tehran constitutes another act of war against Iran by the Israeli regime, says a legal expert.

Bagheri says the Israeli regime's terrorist act has endangered regional and international peace and stability.

Ismail Haniyeh, the slain head of the politburo of the Hamas resistance movement, has been laid to rest in the Qatari capital Doha in a ceremony attended by high-ranking officials from across the region.

Tehran says the zionist regime will soon face severe backlash from justice-seeking nations and governments around the world.

Turkish FM Hakan Fidan has called for the establishment of a security pact in the West Asia region.

Until his final hours, Ismail Haniyeh advocated for the Palestinian cause, leaving behind an illustrious legacy for future generations of freedom-seekers.
