Dubai Telegraph - Iran vows 'crushing' attacks as strikes hit regional infrastructure

Strikes have increasingly targeted economic and industrial sites, raising fears of wider disruption to global energy supplies and deepening the conflict's impact beyond the battlefield.

Iran fired missiles at Tel Aviv overnight, triggering Israeli air defences and leaving four people lightly wounded, while fresh blasts were heard in Jerusalem after the military warned of incoming fire.

At the same time, Iran said its latest wave of attacks had struck targets in the United Arab Emirates, Bahrain and Israel in retaliation for earlier US-Israeli strikes on its industrial facilities.

Iran said targets included "American steel industries in Abu Dhabi, American aluminium industries in Bahrain, and the Rafael arms factories of the Zionist regime".

Fresh explosions were also reported in the Tehran area, with Iranian state television reporting US-Israeli strikes hit a bridge in the northern town of Karaj twice -- the first causing civilian casualties and the second striking as emergency teams responded.

US President Donald Trump -- who on Wednesday threatened to bomb the Islamic republic "back to the Stone Ages" -- maintained his harsh rhetoric as he posted on social media that the bridge had been sent "tumbling down" and promising "much more to follow".

The country's two largest steel plants have also been forced offline by repeated US and Israeli strikes, companies said.

Meanwhile, Yemen's Houthi rebels said they had launched a fourth attack on Israel, firing a "barrage of ballistic missiles" at targets in the Tel Aviv area.

Despite the bombardment in Iran, families gathered in Tehran's Melat Park, with men smoking water pipes and children playing to mark the 13th day after Nowruz, the Persian New Year, when people traditionally picnic outdoors.

A resident said checkpoints manned by Revolutionary Guards had increased across the city.

"They gather in the streets in order to show people that they are still in power and nothing is gonna change," said the 30-year-old man, who requested his name not be used.

In Israel, Passover celebrations continued, though some marked the holiday underground.

"This is not my first choice," said a writer named Jeffrey at a meal in a Tel Aviv bunker.

- Strait tensions -

The conflict has also intensified pressure on global shipping, with the Strait of Hormuz -- a conduit for one-fifth of the world's oil -- effectively closed by Iran.

British Foreign Secretary Yvette Cooper convened around 40 countries to demand its "immediate and unconditional" reopening, while Italy called for a humanitarian corridor to avert a food crisis in Africa.

Tehran said it was drafting a post-war framework with Oman to oversee maritime traffic, though talks have yet to begin.

The head of the Gulf Cooperation Council, Jasem Mohamed AlBudaiwi, meanwhile called for UN backing to protect shipping through the strait, warning that Iran had blocked commercial vessels and imposed conditions on passage.

Bahrain has proposed a draft UN Security Council resolution that would authorise the use of force to ensure free transit, though the US-backed measure has divided members ahead of a vote.

Against that backdrop, Trump has warned that further strikes could target Iran's energy infrastructure if no deal is reached.

He said Washington had "our eyes on key targets", including power plants, while also suggesting Tehran's new leadership could prove "more reasonable" in potential talks.

Iran has dismissed US overtures as "maximalist and irrational", saying messages had been passed through intermediaries but no direct negotiations were underway.

The country's health ministry said the Pasteur Institute, a century-old medical centre in Tehran, had been heavily damaged in a strike.

In Lebanon, Iran-backed militant group Hezbollah said it launched drones and rockets at northern Israel, a day after an Israeli strike in Beirut killed a senior commander, according to two sources. Lebanese authorities said seven people died in the strike.

Eighteen European countries have urged both sides to halt fighting amid fears Israel could seize territory in southern Lebanon.

Amy Pope, head of the International Organization for Migration, warned of "very alarming" risks of prolonged displacement.

- Global shock -

The war's economic impact is rippling far beyond the Middle East, with Gulf states once seen as safe havens now under direct threat.

Air defences in the United Arab Emirates intercepted missiles and drones, while global markets reacted nervously to the latest escalation.

Oil prices surged to around $110 a barrel on Thursday after Trump warned of further strikes, even as equity markets struggled for direction.

Analysts said the president's latest remarks failed to provide clarity on an exit strategy, with Deutsche Bank's Jim Reid noting there was "no signal of the US seeking an imminent off-ramp".

The World Bank warned of mounting risks to inflation, jobs and food security worldwide.

Airlines in China are raising fuel surcharges, while Malaysia has asked civil servants to work from home.

Iraq's oil revenues have plunged more than 70 percent month-on-month, an official said.

Pakistan has also sharply raised fuel prices, with petrol up more than 40 percent and diesel more than 50 percent in response to the global energy shock.

Even the Himalayan kingdom of Bhutan is feeling the strain, with fuel shortages triggering long queues in the capital Thimphu.

"We are helpless," said resident Karma Kalden.
