What we covered today

By

Thank you for reading our rolling coverage of the war in the Middle East. This live blog has closed for the day, but we will resume at 6am on Tuesday.

Here’s what we covered today:

  • US President Donald Trump has threatened to “obliterate” Iranian power plants unless the Strait of Hormuz is reopened, giving the regime a 48-hour deadline, ending at 10.44am on Tuesday (AEDT).
  • Iran’s parliamentary Revolutionary Guard said if the US did that, Iran would respond by hitting power plants in all areas that supplied electricity to American bases, “as well as the economic, industrial and energy infrastructures in which Americans have shares”.
  • Israeli Prime Minister Benjamin Netanyahu warned that Iran’s missiles have the capability to reach “almost everywhere in Europe” after the Iranian regime’s failed attack on a joint UK-US air base on the island of Diego Garcia, 4000 kilometres from Iran. UK Housing Secretary Steve Reed said there was “no specific assessment” by UK agencies that the Iranian regime was targeting the nation or could hit targets there even if it wanted to.
  • International Energy Agency executive director Fatih Birol told the National Press Club in Canberra he fears global leaders aren’t recognising the depths of the fuel crisis. The watchdog is consulting leaders to assess whether more of the world’s oil stores should be released.
  • Israel launched a new wave of attacks against Tehran. A top American commander warned Iranian civilians to stay inside for the foreseeable future, and claimed populated areas where Iran was launching missiles and drones from would be targeted.
  • Israeli Defence Minister Israel Katz expanded the military’s list of targets to include all bridges over the Litani River in southern Lebanon. Israel later struck the Qasmiyeh Bridge near Tyre.
  • The Israeli military said Iran fired intercepted missiles towards Israel. At least 175 people were injured in Iranian missile attacks on the southern Israeli cities of Arad and Dimona, near an Israeli nuclear facility, after air defences failed on Sunday.
  • Air defences in the United Arab Emirates intercepted a ballistic missile near the Al Dhafra Air Base in Abu Dhabi, and one person on the ground was injured when hit with shrapnel.
  • The federal government has commissioned an assessment of Australia’s food supply chain amid persistent fears the war in Iran will further disrupt the export of Middle Eastern oil.

Global LNG exports fall to six-month low

By Stephen Stapczynski

Global liquefied natural gas exports have declined to a six-month low, erasing recent supply additions from the US and elsewhere as the conflict in the Middle East throttles flows.

The 10-day moving average for LNG shipments has fallen about 20 per cent from the start of the month to 1.1 million tonnes, the lowest since September, according to Bloomberg analysis of ship-tracking data on Kpler.

The drop is primarily from Qatar – and to a lesser extent the United Arab Emirates, the data shows. Both nations need to ship fuel through the Strait of Hormuz to reach customers in Asia and Europe.

The US-Israeli war in Iran has spiralled into a regional conflict that has upended the global LNG market. Qatar was forced to shut its LNG export plant in Ras Laffan – the biggest in the world – earlier in the month after Iranian strikes. A further attack last week damaged the facility, and it will take years for two of the plant’s 14 production trains to be repaired.

LNG output around the world had been rising steadily over the past year, thanks primarily to new projects in the US and Canada. This is now being offset by the loss of Qatari LNG and the effective closure of Hormuz – a key waterway for about a fifth of global LNG supply.

‘Stay inside,’ US commander warns Iranians

By

A top American commander has told Iranians to remain in shelters for the foreseeable future.

As we reported earlier, Israel launched a new wave of attacks on Monday against Tehran, with the military saying it had “begun a widescale wave of strikes” on infrastructure targets in the city, without immediately elaborating.

US Central Command chief Admiral Brad Cooper claimed in an interview that Iran was launching missiles and drones from populated areas, and suggested those areas would be targeted.

“You need to stay inside for right now,” Cooper told Iranian civilians in an interview with the Farsi-language satellite network Iran International.

How Iran could cripple the Gulf

By Tom Cotterill, Ben Farmer and Hannah Boland

Iran has threatened to destroy the Middle East’s biggest oil factories in a move that could cripple the Gulf and trigger a global energy crisis.

As well as striking oil fields in Saudi Arabia, Qatar, the United Arab Emirates and Kuwait, Iran could target desalination plants that supply millions in the Middle East with drinking water.

Such an attack could also trigger a cost-of-living emergency, pushing fuel prices to record highs. The threat of tit-for-tat military responses from Iran and the US has also placed a ticking time bomb under global energy markets, analysts have warned.

Although the US and Israel have targeted Iran’s missile capabilities heavily, Tehran is still believed to have the weapons in its arsenal to cause a crisis in the Middle East and beyond.

‘If you hit electricity, we hit electricity’: Iran

By

The Islamic Revolutionary Guard Corps is vowing to retaliate with equal force if the US strikes its electricity assets, Reuters reports.

In a statement addressing US forces, the Revolutionary Guard vowed that “if you hit electricity, we hit electricity”.

The Guard said it was determined to respond to any threat at the “same level” for deterrence. In the event of an attack on power plants, Iran would retaliate against Israel’s power plants, and regional power plants that supply electricity to American bases, it said.

President Donald Trump has threatened to obliterate Iranian power plants unless the Strait of Hormuz is reopened, giving the regime a 48-hour deadline, ending at 10.44am on Tuesday (AEDT).

Japan tries to head off toilet paper panic buying

By Maho Nambu

Japan’s government has urged citizens not to panic buy toilet paper as social media posts suggest people are starting to stockpile daily necessities out of concern over the war in the Middle East.

Hoarding toilet paper became a phenomenon in Japan at the time of the 1973 oil shock, which triggered the country’s first postwar economic contraction. More recently, the devastating earthquake and tsunami of 2011, and the COVID-19 pandemic triggered similar patterns of behaviour.

Australians also hoarded toilet paper during the pandemic.

Japan’s Ministry of Economy, Trade and Industry said in a statement that shoppers should make rational decisions about toilet paper purchases based on accurate information.

Australia’s abundant gas supply a bargaining chip in China, Japan talks

By Mike Foley

Australia is negotiating with Japan, China and other regional powers to ensure critical fuel supplies remain open, with gas shipments from the Middle East to Asia set to run out within days, raising the prospect of the Albanese government imposing price caps or export restrictions on liquefied natural gas.

Shipments of LNG from Qatari gas fields have stopped, with no sign of when they might resume. Those ships will unload their cargoes in 10 days’ time.

The Persian Gulf nation produces about a fifth of the world’s LNG, but was forced to shut down exports after Iran blockaded the Strait of Hormuz and its largest plant was badly damaged in a missile attack last week.

International Energy Agency chief Fatih Birol has warned that the world faces the worst oil market crisis in history, issuing a call for workers to stay home, motorists to drive more slowly and travellers to cut back on flights, to preserve fuel.

Australia imports about 80 per cent of its liquid fuels, and Prime Minister Anthony Albanese said he would use Australia’s gas exports as leverage to ensure Asian nations maintained their exports to the country.

Australian government in daily contact with fuel suppliers, refiners

By Nick Newling

In federal parliament, Opposition Leader Angus Taylor has just asked about shipments of fuel to Australia, to begin question time.

Energy Minister Chris Bowen yesterday said six of 80 impending shipments of oil had been cancelled.

Taylor asked: “When was the government advised six shipments of vital fuel supply down for Australia were cancelled, and as of today, how many ships have been cancelled?”

Prime Minister Anthony Albanese responded saying he was in constant contact with importers. The question was then asked again to Energy Minister Chris Bowen who said the government was in contact with oil refiners Ampol and Viva every day.

Watchdog fears leaders not recognising depth of fuel crisis

By Brittany Busch

The world’s energy watchdog fears the depth of the fuel crisis isn’t being recognised by global leaders, and oil is not the only commodity that will be hit during the war in the Middle East.

International Energy Agency executive director Fatih Birol said his fears had grown by the end of last week.

“Some of the vital arteries of the global economy, such as petrochemicals, such as fertilisers, such as sulfur, such as helium – their trade is all interrupted, which would have serious consequences for the global economy, which is the reason I decided to make statements,” he told the National Press Club in Canberra.

Birol said Australia’s supply of oil – about 38 days’ worth – was a “solid number”, and successive governments had failed to reach the agency’s recommended 90-day stock level.

“I know from this very government that they are doing their best to increase those levels,” he said.

“I very much hope that after this very event, there are some positive steps in that direction, but let’s [not] forget that Australia also makes a major contribution to regional energy security,” he said, referring to Australia’s liquified natural gas exports.

Israel launches ‘wave of strikes’ in Tehran

By

The Israeli military says it has begun a wide-scale wave of strikes targeting Iranian infrastructure in Tehran, Reuters reports.

People on the ground have reported a series of powerful explosions across the city’s central, southern and eastern areas, and Iranian air defence systems have been activated, according to Al Jazeera.
