Former congresswoman Marjorie Taylor Greene has lashed out at President Donald Trump after he made staggering comments on Tuesday threatening to wipe out Iranian civilisation.

“A whole civilisation will die tonight, never to be brought back again,” he wrote in a post on Truth Social on Tuesday.

“I don’t want that to happen but it probably will.”

Greene wrote: “25TH AMENDMENT!!! Not a single bomb has dropped on America. We cannot kill an entire civilization. This is evil and madness.”

The 25th amendment of the US constitution covers the process to remove the American president by a process of impeachment.

Liberal Democrat leader Ed Davey has called on Sir Keir Starmer to withdraw US access to UK air bases to prevent Britain becoming an “accomplice to war crimes”.

In a letter to the prime minister, Mr Davey and 57 other Lib Dem MPs say that if the government refuses, it must “at the very least” formally clarify and publish the conditions placed on the US for use of UK bases to ensure it is only defensive, commit to monitoring the outcome of all sorties and report them to Parliament’s Intelligence and Security Committee.

The Lib Dems are calling on Sir Keir Starmer to withdraw US access to UK bases.

Greens’ leader Zack Polanski also called for the government to “immediately and unequivocally suspend support for the US military”.

“The Government have tried to appease him, then they tried to say they’re standing up to him,” he wrote on social media.

Iran had previously cut off shipping through the strait following attacks by Israel and the US on 28 February, which marked the beginning of the current conflict.

The UK will reportedly refuse to allow Donald Trump to use RAF bases for strikes on Iranian infrastructure, including bridges and power plants, risking the wrath of the volatile US president.

Mr Trump has threatened to unleash “hell” on civilian infrastructure in Iran the blockaded Strait of Hormuz is reopened.

Asked about reports that the US will be blocked from using UK bases for such strikes – first reported by the i Paper – the prime minister’s official spokesperson reiterated that the UK had agreed only for the US to use British bases for “collective self-defence of the region”.

He said: “We won’t be providing a running commentary on our allies’ operations including the use of our bases.

“Our position on this hasn’t changed. The agreement is for US to use bases for collective self-defence of the region, including US defensive operations to degrade missile sites and capabilities used to attack ships in the Straits of Hormuz.”

The spokesperson added: “The principles behind the UK’s approach to the conflict remains the same. We remain committed to defending our people, our interests and our allies, acting in audience with international law and not getting drawn into the wider conflict.”

Iran’s ancient civilisation can be traced as far back as the sixth century BCE.

The country’s population of 92 million descended from the first Aryan tribes and is one of the oldest civilisations on earth.

The Achaemenian dynasty, which lasted from the sixth to the fourth century BCE, was known for its sophisticated art and architecture.

Iranians also contributed to people’s early understanding of maths, astronomy and medicine.

The term Persia was used for centuries, chiefly in the West, to designate those regions where Persian language and culture dominated.

But Iran is highly diverse ethnically and culturally. Persians account for 61 percent of the population, and other groups include Azerbaijanis, Kurds and Turkic groups.

Iran’s language, Farsi is the language in which the great works of Rumi and Omar Khayyam were written.

Authorities in Sharjah in the United Arab Emirates have reported attacks by Iranian missiles on the administrative building of Thuraya telecommunications.

Two people have been injured, according to reports.

Several strikes have been reported across Iran’s railway structure, hours after Israel issued warnings across the country.

A railway in Karaj in Iran was targeted, the Iranian Red Crescent has reported on Tuesday.

Another attack on a railway in Qazvin was also reported by Etemad Online.

A railway bridge in Iran’s Zanjan province was also targeted, Iranian state media reported citing a provincial official.

It follows warnings by Israel that the military would be conducting operations targeting trains and railways.

President Donald Trump has issued a stark threat to Iran on Tuesday, saying that “a whole civilisation will die tonight”.

“A whole civilisation will die tonight, never to be brought back again,” he wrote in a post on Truth Social.

“I don’t want that to happen, but it probably will. However, now that we have Complete and Total Regime Change, where different, smarter, and less radicalized minds prevail, maybe something revolutionarily wonderful can happen, WHO KNOWS?

“We will find out tonight, one of the most important moments in the long and complex history of the World. 47 years of extortion, corruption, and death, will finally end. God Bless the Great People of Iran!”

The astonishing statement comes hours ahead of a deadline imposed by the US for Iran to agree to a deal and reopen the Strait of Hormuz. Iran rejected a 45-day ceasefire proposal and has insisted on a complete cessation of the conflict.

Complaints made by the United States about Nato in recent weeks are pushing Europe to seek alternative security options, Spain’s foreign minister Jose Manuel Albares said on Tuesday.

“Nato is a mutually beneficial alliance for both Europeans and Americans … But the US administration’s remarks and new positions on Euro-Atlantic security are inviting us Europeans to take a leap in terms of our sovereignty and defence matters,” Albares told La Sexta TV channel.

“We must take our citizens’ security and dissuasion into our own hands.”

President Donald Trump had made several remarks about what he perceived as a lack of support over Iran, and said he was “absolutely” considering withdrawing America from the alliance.
