Iran launched missiles and drones at various targets across the Gulf, including a U.S. base in Kuwait, marking its 37th wave of attacks on the 12th day of the ongoing US-Israel war against Iran. These strikes come amid escalating tensions over a global energy crisis, with a vessel burning in the Strait of Hormuz.

The Islamic Revolutionary Guard Corps (IRGC) on Wednesday said it had fired four missiles at the headquarters of US forces in the Middle East, including two missiles targeting Camp Arifjan in Kuwait.

Authorities in Kuwait did not confirm the reports. However, the country’s National Guard said that eight drones targeting the country had been downed.

In the Qatari capital, Doha, several explosions were heard on Wednesday morning as Qatar’s Ministry of Defence said that the country’s military had intercepted a new missile attack aimed at the Gulf nation.

“A little west of the city, we saw interceptions-those smoke clouds when the defensive weapons that Qatar has make contact with those incoming missiles,” Al Jazeera’s Zein Basravi reported from Doha. “These have become a common feature not just here, but across the GCC.”

Saudi Arabia’s Defence Ministry said early on Wednesday it had destroyed five drones heading towards the kingdom’s vast Shaybah oilfield in the Empty Quarter desert. It added that it had intercepted and destroyed two drones in the Eastern Province.

In Bahrain, Iranian attacks wounded dozens, including children, in Sitra near Manama, with a fire breaking out at a Ma’ameer facility after a drone strike.

Earlier, one woman was killed and eight people injured after a drone hit a residential building in Manama.

The United Arab Emirates also said it had responded to incoming missiles and drone threats from Iran.

Meanwhile, the United Kingdom Maritime Trade Operations said an unknown projectile had struck a container vessel in the Strait of Hormuz, some 25 nautical miles (46km) northwest of the UAE’s Ras Al-Khaimah emirate.

The British military said a cargo ship is ablaze. The crew is evacuating and has requested assistance, UKMTO says.

Tensions over the Strait of Hormuz

Concerns are mounting that the war could choke traffic through the Strait of Hormuz, a vital corridor for global oil and gas supplies, driving Brent crude up about 20 percent since the conflict began and already pushing up pump prices worldwide.

The turmoil has rattled financial markets amid fears of prolonged disruption to energy flows.

The US military said on Tuesday it had destroyed 16 Iranian minelayers near the Strait of Hormuz, though President Donald Trump said there were still no confirmed reports that Iran had begun mining the passage, a scenario experts had flagged in the run-up to the war.

Amin Nasser, the president and CEO of Saudi Arabia’s oil giant Aramco, warned on Tuesday that if oil tankers continue to be unable to transit the strait, “that will have a serious impact on the global economy”
