IRGC says it struck US assets in Jordan, Kuwait after 'heavy wave' of US strikes: Saudi Arabia unveils plans for multinational maritime defence coalition

The Islamic Revolutionary Guard Corps said it struck the Azraq military base in Jordan in response, attacking US F-35 fighter jets. The US military denied this, saying no US aircraft had been destroyed or damaged. "All missiles and drones were intercepted, or failed to reach targeted areas," US Central Command said.

US bases in Jordan have lately become primary Iranian targets. Jordan's armed forces said earlier on Thursday they had intercepted five Iranian missiles.

The Guards also struck US assets at Ali Al Salem Air Base in Kuwait, according to Iran's semi-official Tasnim news agency.

An Iranian attack hit a building owned by a Chinese company in northern Kuwait, killing a worker and inflicting significant damage, Kuwait's Defence Ministry said.

In a first in the five-month war, Saudi Arabia on Wednesday publicly joined strikes alongside US forces, targeting Iran-aligned groups in eastern Iraq, in retaliation for drone attacks on Saudi oil targets launched from Iraq.

Trump said he would hit Iran hard for firing missiles at US forces, but that Washington was also still seeking a peace deal to end a conflict that has roiled global energy and finance markets.

Oman has presented Iran with a plan backed by Gulf states to manage the Strait of Hormuz, including collecting voluntary fees for using it, sources told Reuters.

Tehran rejected the Omani proposal on Wednesday, but Iran's semi-official ILNA news agency quoted the country's foreign ministry spokesperson Esmaeil Baghaei as saying that talks with Oman over the Strait of Hormuz were continuing.

Jordan's military said that its air defences shot down five Iranian missiles targeting its territory, adding the attack caused no casualties. Iran's Revolutionary Guards later confirmed launching an attack on Jordan's Al Azraq air base, saying they targeted US aircraft there.

In a statement, US Central Command also said the commercial vessel M/T Nora had not broken through America's blockade of Iranian ports, denying a claim it said was made on Iranian state media.

Oil prices fell despite another night of attacks by Iran and the United States.

Briefing.com analyst Patrick O'Hare said traders were reassured the attacks did not target Iran's oil infrastructure. Brent North Sea Crude: DOWN 0.9 percent at $87.29 per barrel; West Texas Intermediate: FLAT at $84.44 per barrel.
