Iran launched a new wave of attacks targeting American interests across Jordan, Bahrain and Kuwait on Wednesday, escalating a conflict that has already disrupted shipping through the Strait of Hormuz and drawn the region deeper into war.

The strikes came after Tehran vowed "severe punishment" for fresh US attacks on Iranian territory, including a strike that Iranian authorities said hit a home hosting a wedding celebration and killed four people, including a child.

Iran's Revolutionary Guards said they had carried out an "intense ballistic missile attack" targeting Camp Titin, a US Marine Corps base in Jordan.

Jordan's military said it intercepted 10 ballistic missiles fired from Iran. It did not confirm any casualties or damage at the US training camp near the Gulf of Aqaba, close to the borders with Israel and Saudi Arabia. Three other missiles landed in remote areas, the army said.

Sirens in Bahrain, attacks reported in Kuwait

The escalation was not limited to Jordan.

Missile and drone attacks were also reported in Kuwait, where the military said it was responding to Iranian hostilities. In Bahrain, AFP reporters heard airborne attack sirens early Wednesday.

The attacks followed a fresh round of US strikes on Iranian targets on Tuesday.

Iranian state television reported explosions in the country's south near the strategic Strait of Hormuz, as well as on an island in the Gulf. It also reported that US forces had struck an airport in Iran's southern Kerman province.

The Iranian Red Crescent said shrapnel from a US missile strike hit a house where a wedding celebration was underway in the city of Kuhestak. Four people were killed and more than 50 others wounded, according to the organisation.

Iran's official IRNA news agency separately reported that four projectiles struck areas in the counties of Chabahar and Konarak, without providing details about possible damage.

US rejects claims over civilian casualties

Asked about reports of civilian casualties from Tuesday's strikes, US Central Command spokesperson Captain Tim Hawkins said the American military "never targets civilians", accusing Iran's Revolutionary Guards of doing so.

CENTCOM had earlier said the strikes were launched in response to what it described as recent attempted attacks by Iran's Revolutionary Guards against commercial shipping in the Strait of Hormuz and American troops deployed in the region.

US President Donald Trump said the latest American strikes were retaliation for what he described as an Iranian attempt to place sea mines in the Strait of Hormuz and a missile attack targeting a US military base in Jordan.

Iran's Revolutionary Guards, however, warned that Washington would face consequences.

Spokesman Hossein Mohebi said the United States would regret its latest attacks, warning that "severe punishment awaits the aggressors".

Strait of Hormuz remains at the centre of the conflict

The latest exchange comes amid a prolonged war that has left both sides locked in a military and economic confrontation.

Iran has kept the Strait of Hormuz closed, while the United States has maintained a counter-blockade on Iranian ports. The strategic waterway previously carried around one-fifth of the world's oil supplies.

Washington said its forces struck Iranian rocket launchers on Larak island on Sunday, claiming the operation was aimed at preventing Tehran from placing mines along key shipping routes in the strait.

The wider Middle East war began in late February following US and Israeli attacks on Iran that killed Supreme Leader Ayatollah Ali Khamenei.

A subsequent ceasefire between Washington and Tehran collapsed after attacks on commercial vessels in the Strait of Hormuz.

Iran signals diplomacy, but warns against US pressure

Even as military tensions intensified, Iranian President Masoud Pezeshkian said Tuesday that Tehran was prepared to respond if Washington moved towards a deal aimed at ending the war.

But he warned that any return by the United States to what he called a policy of pressure and threats could derail diplomatic efforts.
