Yemen's Houthis enter Iran war, while US Marines arrive in region

The risk of an expanded Iran war grew as Yemen's Houthis on Saturday launched their first attacks on Israel since the start of the conflict, as additional US forces reached the Middle East.

Washington has dispatched thousands of Marines to the Middle East in the month-old war. The first of two contingents arrived on Friday on an amphibious assault ship, the US military said on Saturday.

The Washington Post reported on Saturday that US officials said the Pentagon was preparing for weeks of ground operations in Iran, possibly involving raids by Special Operations and conventional infantry troops. Whether President Donald Trump would approve plans for deploying ground troops remained uncertain, the Post reported.

Reuters has reported the Pentagon was considering military operations that could include deploying ground troops in Iran.

The war, launched on February 28 with US and Israeli strikes on Iran, has spread across the Middle East, killing thousands and hitting the world economy with the biggest-ever disruption to global energy supplies.

Secretary of State Marco Rubio said on Friday the US could achieve its aims without ground troops but that it was deploying some to the region so Trump would have "maximum" flexibility to adjust strategy.

The Pentagon was also expected to deploy thousands of soldiers from the US Army's 82nd Airborne Division.

Iranian President Masoud Pezeshkian spoke to Prime Minister Shehbaz Sharif of Pakistan, which hosts talks from Sunday with the Turkish and Saudi foreign ministers on ways to ease regional tensions.

Israel carried out a wave of attacks on Tehran on Saturday, targeting what Israel's military said was Iranian government infrastructure.

It also hit targets in Lebanon, resuming its war against Hezbollah, killing three Lebanese journalists in a strike on a media vehicle, Lebanon's Al Manar TV reported, as well as a Lebanese soldier. A follow‑up strike on the rescue workers sent to assist them also caused fatalities.

Iran kept up attacks on Israel and several Gulf states after hitting an air base in Saudi Arabia on Friday and wounding 12 US military personnel, two of them seriously, in one of the most serious breaches of US air defences so far.

Israel, which regularly faced missile attacks from the Houthis before the war, confirmed a missile had been fired at it from Yemen. There were no reports of casualties or damage.

Trump has threatened to hit Iranian power stations and other energy infrastructure if Iran does not open the Strait of Hormuz. But he extended a deadline he had imposed for this week, giving Iran another 10 days to respond.

Iranian threats to attack ships in the strait have kept most oil tankers from attempting the waterway. Iran has agreed to let an additional 20 Pakistani-flagged vessels pass through the strait, with two ships permitted to transit daily, said Pakistani Foreign Minister Ishaq Dar.

Israel has targeted Iran's nuclear infrastructure. The head of Russia's state nuclear corporation Rosatom, which has evacuated staff from the Bushehr nuclear power plant on the Gulf coast, said the attacks threatened nuclear safety.

Pezeshkian said Iran would "retaliate strongly if our infrastructure or economic centers are targeted".

Iranian attacks were reported in multiple areas across the Gulf, including Kuwait, the UAE and Oman.

An Iranian airstrike hit the Israeli village of Eshtaol, near Jerusalem. Seven people were hospitalised, Israel’s ambulance service said. Aluminium Bahrain said its facilities were targeted in an Iranian attack on Saturday, Bahrain's state news agency reported.

In Iran, media said at least five people were killed in a US-Israeli attack on a residential unit in the northwestern city of Zanjan, and in Tehran, the Iran University of Science and Technology was struck.
