Iran’s state media is reporting any attack on the country’s southern coast and islands will lead to Gulf routes being cut with the laying of sea mines.

The US is considering plans to occupy or blockade Iran’s Kharg Island, the country’s main oil export hub, to pressure Tehran to reopen the Strait of Hormuz to all shipping, according to Axios.

‘Any attempt to attack Iran’s coasts or islands will cause all access routes in the Gulf (…) to be mined with various types of sea mines, including floating mines that can be released from the coast,’ a statement from , Iran’s Defence Council said today.

‘In this case, the entire Gulf will practically be in a situation similar to the Strait of Hormuz for a long time (…) One should not forget the failure of more than 100 minesweepers in the 1980s in removing a few sea mines.’

The Defence Council recalled that non-belligerent states can only pass through the Strait of Hormuz by coordinating passage with Iran.

The FTSE 100 plunged into the red once again this morning to reach a three-month low, as President Trump stepped up his threats against Iran over the weekend.

London’s main index lost 1.75 per cent, or 170 points, at the open, after losing 3.34 per cent last week to finish at 9,918.33, the lowest since the end of December.

Investors are retreating after Trump’s threats over the weekend to ‘obliterate’ Iran’s power plants if it did not reopen the Strait of Hormuz by the end of today. Iran warned that it would target more of the region’s energy sites in retaliation.

Reports of preparations being made for US troops on the ground in Iran are also causing concern, as investors brace for a protracted conflict.

Elsewhere, Iran declared force majeure on oilfields run by foreign companies, which prompted another surge in brent crude, which reached $118 a barrel at one point last week before closing at $112.19. It climbed 1 per cent to $113 this morning.

Israel’s military said its own artillery fire killed an Israeli civilian close to where forces are fighting Hezbollah.

The civilian was killed yesterday near Israel’s northern border with Lebanon.

After opening an investigation, the military said ‘the initial findings suggest that the Israeli civilian was killed by IDF artillery fire conducted to support IDF soldiers operating in southern Lebanon’.

The IDF added that ‘several severe issues and operational errors took place during the incident, including both the planning and execution of the fire’.

Sir Keir Starmer is expected to chair a Cobra meeting today on the war in the Middle East following talks with Donald Trump

The leaders spoke last night about the need to reopen the Strait of Hormuz.

A Downing Street spokesperson said: ‘The Prime Minister spoke to the President of the United States, Donald Trump, this evening.

‘The leaders discussed the current situation in the Middle East, and in particular, the need to reopen the Strait of Hormuz to resume global shipping.

‘They agreed that reopening the Strait of Hormuz was essential to ensure stability in the global energy market. They agreed to speak again soon.’

China has warned further attacks in the Middle East risk is creating an ‘uncontrollable situation’ in the region as Donald Trump threatens to ‘obliterate’ Iran’s power plants.

The conflict and its impact on Hormuz has threatened global energy security as well as China’s oil supplies and the ‘use of force will only lead to a vicious cycle’, Chinese foreign ministry spokesman Lin Jian told a news conference, when asked about Trump’s threats.

‘If the war expands further and the situation deteriorates again, the entire region could be plunged into an uncontrollable situation,’ he said.

Beijing is a partner of Iran, which has been targeted by US-Israeli attacks since last month, but has also said it ‘does not go along’ with Tehran’s strikes against Gulf states housing US military bases and urged a ceasefire.

Trump, who was due to visit Beijing this month but delayed his trip to deal with the fallout from the war, had called on China and other countries to help reopen the Strait of Hormuz.

Trump gave Tehran a 48-hour deadline on Saturday to end its partial blockade of the Strait of Hormuz, the narrow waterway into the Gulf through which about one-fifth of the world’s oil flows, or risk an attack on its vital energy infrastructure.

European stock markets extended heavy losses at the start of trading today following sharp falls in Asia as oil prices jumped on the escalating Iran war.

London’s benchmark FTSE 100 index shed 1.4 per cent, Paris lost 1.7 per cent and Frankfurt tumbled 2.0 per cent.

In Asia, South Korea’s benchmark Kospi index and Japan’s Nikkei sharply dropped in early trade.

The Kospi was down 4.69 percent at 5,509.88 points. The Nikkei 225 was down 3.54 percent at 51,483.91 points.

Chris Beauchamp, Chief Analyst at IG commented: ‘Investors who have spent the weekend watching fresh strikes in the Middle East are now waiting to see what will happen when Trump’s 48 hour deadline expires tonight.

‘But they are in no mood to hang around, and have continued to sell stocks and precious metals. Each day that the war goes does more damage to the global economy and drives inflation higher, with recession chances rising by the hour.’

Power cuts have been reported across Tehran today after the latest Israeli airstrikes rained down on Iran’s capital.

According to the New York Times, multiple people living in different neighbourhoods of the city are reporting outages.

Powerful explosions were reported across central, southern and eastern Tehran, with Iranian air defence systems activated throughout the capital, according to Al Jazeera Arabic.

Middle East Eye has reported residents using torches in Khorramabad, west of Tehran, where a building was destroyed by bombing.

Iran’s Fars news agency reported airstrikes had targeted five areas of the Iranian capital while Israeli military said it had ‘begun a wide-scale wave of strikes targeting Iranian terror regime infrastructure’.

Donald Trump has promised the ‘total decimation’ of Iran as reports emerged of American plans for a lengthy ground war in the Middle East with thousands of US marines arriving in the region this week.

Amid reports he is ready to send his troops, Mr Trump promised that the destruction of Iran would ‘work out very good’ and the rogue state is ‘getting their comeuppance’.

He may seize Kharg Island, Iran’s oil terminal in the Persian Gulf, although the White House insists no final decision has been made.

Iran has ferociously rejected President Trump’s ultimatum to reopen the Strait of Hormuz by Midnight tonight, UK time, and threatened to wipe out the entire region’s energy infrastructure.

Trump warned Tehran on Saturday it had 48 hours to allow cargo through the vital global shipping lane ‘without threat’ or he would ‘obliterate’ their power plants.

But the regime hit back yesterday saying if its plants were targeted then energy infrastructure ‘across the entire region’ would be ‘irreversibly destroyed’.

International Energy Agency Executive Director Fatih Birol

The global economy is under ‘major threat’ from the energy crisis caused by the Middle East war, International Energy Agency chief Fatih Birol said.

Speaking at the National Press Club in Australia’s capital, Birol warned ‘no country will be immune’ to its effects.

He compared the current energy crisis to those of the 1970s and the impact of Russia’s 2022 invasion of Ukraine.

‘This crisis as things stand is now two oil crises and one gas crash put all together,’ he said.

‘The global economy is facing a major, major threat today, and I very much hope that this issue will be resolved as soon as possible,’ Birol added.

‘No country will be immune to the effects of this crisis if it continues to go in this direction. So there is a need for global efforts.’

Explosions rang out in Tehran early this morning as Israel announced it launched a fresh wave of strikes.

Iran’s Fars news agency reported airstrikes had targeted five areas of the Iranian capital while Israeli military said it had ‘begun a wide-scale wave of strikes targeting Iranian terror regime infrastructure’.

Israel has also expanded its ground campaign against Iran-allied Hezbollah in Lebanon, warning of a lengthy operation there.

‘Citizens of Israel, we face more weeks of fighting against Iran and Hezbollah,’ Israeli military spokesman Brigadier General Effie Defrin said.

Israeli forces were given orders to destroy bridges they said were used by Hezbollah to cross the key Litani river, 30 kilometres (20 miles) north of the border.

More than 1,000 people have died in Lebanon since Israel launched strikes, according to the health ministry, with more than one million people displaced.

Saudi Arabia and the United Arab Emirates reported coming under fresh attacks this morning, with explosions and sirens sounding over the oil-rich Gulf.

The Saudi Ministry of Defense said it had detected two incoming ballistic missiles targeting the capital on Monday, ‘one of which was intercepted and the other fell in an uninhabited area’.

The UAE defence ministry said it was ‘currently responding to incoming missile and drone threats from Iran’, explaining ‘the sounds heard are the result of the Air Defence Systems intercepting missiles and drones’.

Hours earlier, Abu Dhabi authorities reported an Indian national had been wounded by falling debris from an intercepted ballistic missile.

And sirens were sounding in Bahrain, with residents instructed to seek shelter.

‘Citizens and residents are urged to remain calm and head to the nearest safe place,’ the interior ministry posted on social media.

Gulf nations that have long billed themselves as oases of safety and stability in the region have been drawn into the Middle East war as Iran retaliates against US-Israeli strikes.

Iran today faces a deadline by President Donald Trump to open up the crucial Strait of Hormuz or face a major US assault on power plants, as Israel warned of weeks more of war.

Trump and Tehran traded threats as the war entered its fourth week, with the US president demanding the Islamic republic reopen the blocked Strait of Hormuz, through which some 20 per cent of the world’s oil and gas shipments transit.

The bottleneck has nearly halted all petroleum shipments through the narrow waterway, and oil prices have spiked.

Trump posted late Saturday on Truth Social that US forces would ‘hit and obliterate’ Iranian power plants – ‘starting with the biggest one first’ – if Tehran did not fully reopen the strait within 48 hours, or 23:44 GMT on Monday, according to the time of his post.

In response, Iran’s army said it will target energy and desalination infrastructure ‘belonging to the US and the regime in the region,’ according to the Fars news agency.
