Israel says its military has attacked Houthi targets at three ports and a power plant in Yemen.

Defence minister Israel Katz confirmed the strikes, saying they were carried out due to repeated attacks by the Iranian-backed rebel group on Israel.

Mr Katz said the Israeli military attacked the Galaxy Leader ship which he claimed was hijacked by the Houthis and was being used for “terrorist activities in the Red Sea”.

It came after the Israel Defense Forces (IDF) issued an evacuation warning for people at Hodeidah, Ras Issa, and Salif ports – as well as the Ras al Khatib power station, which it said is controlled by Houthi rebels.

The IDF said it would carry out airstrikes on those areas due to “military activities being carried out there”.

Afterwards, Mr Katz confirmed the strikes at the ports and power plant.

Earlier in the day, a ship was reportedly set on fire after being attacked in the Red Sea.

A private security company said the assault, off the southwest coast of Yemen, resembled that of the Houthi militant group.

It was the first such incident reported in the vital shipping corridor since mid-April.

The vessel, identified as the Liberian-flagged, Greek-owned bulk carrier Magic Seas, had taken on water after being hit by sea drones, maritime security sources said. The crew later abandoned the ship.

The Houthi rebels have been launching missile and drone attacks against commercial and military ships in the region in what the group’s leadership called an effort to end Israel’s offensive against Hamas in Gaza.

Between November 2023 and January 2025, the Houthis targeted more than 100 merchant vessels with missiles and drones, sinking two of them and killing four sailors.

The Houthis paused attacks in a self-imposed ceasefire until the US launched an assault against the rebels in mid-March.

That ended weeks later and the Houthis have not attacked a vessel, though they have continued occasional missile attacks targeting Israel.

A renewed Houthi campaign against shipping could again draw in US and Western forces to the area.

The ship attack comes at a sensitive moment in the Middle East.

A possible ceasefire in the Israel-Hamas war hangs in the balance and Iran is weighing up whether to restart negotiations over its nuclear programme.

It follows American airstrikes last month, which targeted its most-sensitive atomic sites amid an Israeli war against the Islamic Republic that ended after 12 days.

How did the Houthis come to control much of Yemen?

A civil war erupted in Yemen in late 2014 when the Houthis seized Sanaa.

Worried by the growing influence of Shia Iran along its border, Saudi Arabia led a Western-backed coalition in March 2015, which intervened in support of the Saudi-backed government.

The Houthis established control over much of the north and other large population centres, while the internationally recognised government based itself in the port city of Aden.

Under the red flag of martyrdom, they beat their chests in memory of a fallen religious leader as the cleric recounts his fate outside one of Tehran’s oldest mosques.

Imam Hussein was tricked and martyred by his enemies in the seventh-century battle of Karbala. The crowd of grown men and women wept with grief as Hussein’s story was retold on Sunday.

Ashura is always deeply moving for the Shia faithful but this year even more so. It comes after the trauma of Israel’s surprise attacks on Iran.

There was a sense of emotional release and a chance for Iranians to come together in solidarity.

Ashura is also a reminder that Iran’s revolutionary leaders draw much of their power from the strength of religion in this country after a conflict its enemies hoped would see those same leaders toppled.

The festival has come at just the right time for its embattled government.

Iran’s supreme leader has appeared in public for the first time since Israel attacked his country. Ayatollah Ali Khamenei was greeted with ecstatic cheers by his followers at Ashura prayers.

His supporters told us they welcomed his return. “I was so happy that I didn’t know what to do,” said one woman. “This caused our big enemies the United States and Israel to receive a great slap in the mouth.”

“His appearance on TV for Ashura,” a young man told us, “showed that all the talk about him hiding and taking the path of peace with the United States is not true and it shows that he is holding his position strongly and steadfastly”.

Defiance in Tehran as Khamenei makes appearance

We had been given rare access to Iran among a handful of journalists who were let in after the 12-day war.

Its scars aren’t hard to find – buildings left with gaping holes where Israeli airstrikes took out members of Iran’s elite, one after another.

And Abbas Aslani, an analyst with close ties to the government, says there is a fear it may not be over.

“The Iranian government and the army are prepared for a new round of conflict, because they think that the other party, specifically Israel, is not to be trusted in terms of any ceasefire,” he said.

At the Ashura ceremony, the crowd chants, “we’ll never yield to humiliation” – an age-old message for Iran’s enemies today as they brace for the possibility of more conflict.

They rose to their feet in ecstatic surprise, shouting “heydar, heydar” – a Shia victory chant.

This was the first public appearance of their supreme leader since Israel began attacking their country.

He emerged during evening prayers in his private compound. He said nothing but looked stern and resolute as he waved to the crowd.

He has spent the last weeks sequestered in a bunker, it is assumed, for his safety following numerous death threats from Israel and the US.

His re-emergence suggests a return to normality and a sense of defiance that we have witnessed here on the streets of Tehran too.

Earlier, we had filmed as men in black marched through the streets of the capital to the sound of mournful chants and the slow beat of drums, whipping their backs with metal flails.

This weekend they mark the Shia festival of Ashura as they have for 14 centuries. But this year has poignant significance for Iranians far more than most.

The devout remember the betrayal and death of Imam Hussein as if it happened yesterday. We filmed men and women weeping as they worshipped at the Imamzadeh Saleh Shrine in northern Tehran.

The armies of the Caliph Yazid killed the grandson of the Prophet Muhammad in the seventh-century Battle of Karbala.

Shiite Muslims mark the anniversary every year and reflect on the virtue it celebrates, of resistance against oppression and injustice.

But more so than ever in the wake of Israel and America’s attacks on their country.

The story is one of prevailing over adversity and deception. A sense of betrayal is keenly felt here among people and officials.

Many Iranians believe they were lured into pursuing diplomacy as part of a ruse by the US.

Iran believed it was making diplomatic progress in talks with America it hoped could lead to a deal. Then Israel launched its attacks and, instead of condemning them, the US joined in.

Death to Israel chants resounded outside the mosque in skies which were filled for 12 days with the sounds of Israeli jets. There is a renewed sense of defiance here.

One man told us: “The lesson to be learned from Hussein is not to give in to oppression even if it is the most powerful force in the world.”

A woman was dismissive about the US president. “I don’t think about Trump, nobody likes him. He always wants to attack too many countries.”

Pictures on billboards nearby draw a line between Imam Hussein’s story and current events. The seventh-century imam on horseback alongside images of modern missiles and drones from the present day.

Other huge signs remember the dead. Iran says almost 1,000 people were killed in the strikes, many of them women and children.

Officially Iran is projecting defiance but not closing the door to diplomacy.

Government spokeswoman Dr Fatemeh Mohajerani told Sky News that Israel should not even think about attacking again.

“We are very strong in defence and as state officials have announced, this time Israel will receive an even stronger response compared to previous times,” she said.

“We hope that Israel will not make such a mistake.”

But there is also a hint of conciliation: Senior Iranian officials have told Sky News that back-channel efforts are under way to explore new talks with the US.

Israel had hoped its attacks could topple the Iranian leadership. That proved unfounded, the government is in control here.

For many Iranians, it seems quite the opposite happened – the 12-day war has brought them closer together.
