Hezbollah chief warns any war against Iran would engulf region

The head of the Lebanon's Hezbollah group warned on Friday that if there was a war against Iran the whole Middle East region would "erupt", amid escalating US-Iranian tensions.

"[US President Donald] Trump, his administration, and his intelligence know well that any war on Iran will not remain confined to Iran's borders," Hassan Nasrallah said.

"Any war on Iran will mean the whole region will erupt," said the head of the Iran-backed group in a televised speech, explaining that such a war was therefore unlikely.

"And any American forces and American interests will be permissible," as a target, he said.

Hezbollah is listed as a "terrorist group" by the United States, and has fought several wars with US-ally Israel to the south of Lebanon.

In 2006, Israel had launched a war against Hezbollah during which at least 1,200 people, mostly Lebanese civilians, were killed.

Nasrallah on Friday also slammed a proposed US peace deal to end the Israeli-Palestinian conflict that Trump has dubbed "the deal of the century".

"It's a void deal... a historic crime," he said of the plan, that has already been rejected by the Palestinians as it is expected to largely favour Israel.

"This deal is a loss of Palestinian, Arab, and Islamic rights," Nasrallah said.

The Muslim Brotherhood and Iran have also rejected the US 'peace plan.'

Thousands of Iranians joined annual rallies in support of the Palestinian cause on Friday.

Trump's son-in-law Jared Kushner has been drafting the long-awaited peace plan, the economic aspects of which are to be presented at a conference in Bahrain next month.

The United Nations earlier on Friday said it would not be taking part in that meeting on June 25 and 26 in Manama.

Gulf countries in Mecca expressed "support for the US strategy towards Iran", which includes crippling sanctions and deploying an aircraft carrier task force, B-52 bombers and an amphibious assault ship to the Gulf.

Nasrallah warned that Hezbollah was a force to reckon with.

"We have precision missiles in Lebanon, and enough to be able to change the face of the region," he said.

The group has been backing the Damascus regime in the civil war in neighbouring Syria, and stands accused of also backing rebels in the conflict in Yemen.

US President Donald Trump unilaterally recognised Jerusalem as the capital of Israel on December 6, 2017, triggering world outcry and it relocated its embassy in Tel Aviv to Jerusalem on May, 2018. 

Guatemala has followed the US suit, relocating its embassy to the occupied city.

Jerusalem remains at the core of the Israel-Palestine conflict, with Palestinians hoping that East Jerusalem – now occupied by Israel – might eventually serve as the capital of a future Palestinian state.
