Pro-Iran protesters brandish billboards depicting the Iranian Supreme Leader Ali Hosseini Khamenei, flags of Yemen and Iran, weapons, and chant slogans as they take part in a rally held to condemn the US-Israel aerial attacks on Iran.

• Iran threatened to confiscate the property of Iranians living in the West who support US and Israeli strikes.
• At least five million Iranians live abroad, most of them in the ⁠US and Western Europe.
• Heavy explosions rocked the Iranian capital, Tehran, on Monday.

Iranians living ‌abroad could have property confiscated and face other legal penalties if they express ‌support for the United ⁠States and Israel, the Iranian prosecutor ⁠general’s office said on Monday.

Some members of the Iranian diaspora who want political change in Tehran took to ‌the streets of European and American cities to celebrate the killing of Supreme Leader Ayatollah Ali Khamenei ‌in the US-Israeli war against Iran.

Iran on Monday named Mojtaba Khamenei to succeed his father.

“A warning has been issued to those Iranians ‌living abroad who ⁠in different ways sympathise, support or cooperate with the American-Zionist (Israeli) enemy,” the prosecutor general’s office was quoted as saying by state media.

“They will be met with the confiscation of all their properties and other legal penalties in accordance with the law.”

Newly established channels on Telegram ⁠have shared details of prominent Iranians living abroad who have posted comments critical of Iran’s clerical authorities and supportive of the US-Israeli ⁠military campaign that began on 28 February.

Up to five million Iranians live abroad, most of them in the ⁠US and Western Europe, according to ‌Iranian government data.

‌Iranian media put their numbers closer to 10 million.

Heavy explosions rocked the Iranian capital on Monday, AFP journalists said, as the war with Israel and the US raged.

It was not immediately clear what was targeted in Tehran, but the blasts were heard across several parts of the city, the reporters said.

But Israel’s military said it struck targets in central Iran on Monday, including internal security command centres and missile launch sites, in the first raid since the Islamic republic appointed a new supreme leader.

“The Israeli Air Force... completed an additional wave of strikes on infrastructure across Iran belonging to the Iranian regime,” a military statement said.

The targets included “a rocket engine production facility and several long-range ballistic missiles launch sites” that threatened Israel, it said.

The internal security headquarters in the central city of Isfahan, a police headquarters and other facilities used by the Revolutionary Guards and paramilitary Basij force were also hit, according to the military.

AFP reported that Iran launched fresh strikes on energy installations in the Gulf on Monday, including a petroleum complex in Bahrain, as oil prices soared on fears over supply disruptions due to the Middle East war.

Bahrain said the attack on its Al Ma’ameer oil facility had caused a fire, but the blaze had been brought under control.

Several explosions were also heard on Monday in the Qatari capital Doha, AFP journalists said, as Qatar, Saudi Arabia, the UAE and Kuwait all reported new attacks.

Doha has been targeted by waves of drones and missiles since Iran launched a retaliation campaign across the Gulf in the wake of US and Israeli attacks against the Islamic Republic.

Qatar’s defence ministry said on Monday that its forces had intercepted a missile attack.

Saudi Arabia’s defence ministry said the kingdom intercepted and destroyed two waves of drones heading towards the Shaybah oil field in the southeast of the country.

In the UAE, authorities said in a statement on X that air defences responded to “a missile threat”.

Kuwait, which was targeted by seven missiles and five drones on Sunday, according to authorities, announced another missile and drone attack on Monday.

The defence ministry said air defences were working to intercept the attack.

Gulf countries have borne much of Tehran’s response after the US and Israel launched a massive aerial campaign against Iran.

Stranded passengers have been paying huge sums of money to escape the Middle East, with last-minute dashes to the airport, overland trips to less impacted hubs and, at times, fighter jets escorting passenger planes out.

With most airspace in the region still closed over missile and drone concerns, some people ‌have turned to private jets as charter flights and limited commercial services struggle to evacuate tens of thousands of travellers.
