Houthi Blockade On Saudi Red Sea Oil Transits Threatens To Widen War, Strangle Energy Supply (Updated)
As renewed hostilities between Iran and the U.S. and its allies enter a 10th day, the Houthi rebels of Yemen say they are imposing an embargo on Saudi oil shipments passing through the Bab el-Mandeb (BAM) Strait. The move threatens to add further pressure on oil exports from the Middle East, already drastically affected by the Iranian closure of the Strait of Hormuz and the resumption of the U.S. blockade on Iranian ports. Saudi Arabia has diverted millions of barrels of oil per day through pipelines to its Yanbu port on the Red Sea in an effort to minimize the energy shortages due to the hostilities in the Persian Gulf. This also raises the specter of the U.S. having to get as involved as it did during the previous Houthi campaign against shipping that ended last September, which could pull resources away from Iranian-focused operations.
Meanwhile, President Donald Trump renewed threats against Iran over the recent deaths of U.S. troops while reports have emerged that he is considering widening the conflict. However, the massive expenditure of air defense munitions that has already taken place is a major consideration. In addition, there are growing concerns about the extent of the damage to U.S. bases in the region and the uptick in casualties.
On Monday, Kuwait said it came under Iranian fire again.
“Kuwaiti air defenses are currently engaging hostile missile and drone attacks following the heinous Iranian aggression,” the Kuwaiti Defense Ministry stated on X. “The General Staff of the Army notes that any sounds of explosions heard are a result of air defense systems intercepting hostile attacks. Everyone is urged to adhere to the security and safety instructions issued by the relevant authorities.”
Hours earlier, Bahrain said it too had come under a new wave of Iranian attacks.
“The General Command of the Bahrain Defense Force (BDF) announces that Iran is continuing its systematic hostility approach through its sinister attacks targeting civilians in the Kingdom of Bahrain,” BDF posted on X. “The General Command clarifies that, with strong will and high combat readiness, the air defense systems attacked, intercepted and destroyed a number of treacherous Iranian air strikes today, Monday, July 20, 2026.”
The extent of the damage in either Kuwait or Bahrain is unclear at the moment. These most recent attacks came after U.S. Central Command on Sunday night said it wrapped up a ninth straight day of strikes on Iranian assets, targeting “military command centers, air defense and coastal surveillance sites, maritime capabilities, missile and drone launch sites, and communications networks to further diminish Iran’s ability to attack commercial vessels and civilian mariners transiting the Strait of Hormuz,” the command stated on X.
Amid this kinetic activity, as we noted earlier in this story, the Iranian-backed Houthis say they will no longer permit Saudi Arabian ships passage through from the Red Sea into the Bab el-Mandeb Strait.
“The Yemeni Armed Forces declare a maritime embargo against the criminal Saudi enemy, based on the equation of an ‘eye for an eye,’ effective immediately upon the issuance of this statement,” the Houthis stated on Monday, according to the official Houthi SABA media outlet. The move follows increased tensions between the Houthis and Saudi Arabia as well as a request by Iran “to stand ready to close the Red Sea oil route if the United States strikes Iranian power infrastructure,” Reuters reported last week. “The idea has been discussed within the Islamic Republic’s leadership, and the message has been conveyed to Iran’s Houthi allies.”
Houthi forces on Monday reportedly began issuing warnings on open maritime frequencies near Yemen that the BAM is closed to Saudi shipping and its vessels are subject to attack.
A Houthi shut down of the Bab el-Mandeb (BAM) Strait, a narrow stretch of water between Yemen and Djibouti, would choke off the flow of oil exports from Saudi Arabia, exacerbating the above-mentioned impingement on the flow of oil from the closed Strait of Hormuz.
Having both straits closed at once is something of a ‘sum of all fears’ scenario for the global energy marketplace.
“The full closure of the BAM would cut global oil supply by 7% as it would leave most Saudi oil exports unable to leave the region,” Reuters noted on Monday. “The disruption would add to the massive cut to global oil flows from the war in the Gulf, which has already reduced shipments by 10% of global supply.”

Beyond affecting the flow of oil, a Houthi blockade on the BAM threatens to open a new front in this conflict.
The Houthis carried out a campaign against shipping in November 2023 in solidarity with Palestinians over the latest war between Israel and Gaza. However, while it was ostensibly aimed at only Israeli connected ships, numerous commercial vessels with no clear Israeli ties were attacked as were several U.S. and allied warships. The campaign stretched into the summer of 2025, forcing some vessels to avoid the Suez Canal for a far longer route around Africa, boosting shipping costs by nearly $200 billion at the time.
The Houthi attacks also forced the U.S. and allies to deploy many warships, including the Eisenhower and Truman Carrier Strike Groups (CSG) to both defend against Houthi attacks and strike targets in Yemen. These operations resulted in a large expenditure of air defense and strike munitions.

The possibility exists that a new wave of Houthi attacks — especially if non-Saudi ships are targeted — could drag in U.S. forces already in heavy use in the Persian Gulf region battling the Iranians. This sets up a major showdown as Saudi oil is a lifeline to Asian supplies hobbled by conflict in the Persian Gulf. We reached out to CENTCOM for comment and will update this story with any pertinent details shared.
Earlier on Monday, the head of the European-led task force providing maritime security in the Red Sea region told us the Houthis remain a threat to navigation despite not having attacked any merchant vessels since September 2025.
“The security situation in the Bab el-Mandeb remains fragile and is highly sensitive to regional escalation,” Rear Admiral Vasileios Gryparis, Commander of EUNAVFOR ASPIDES, told TWZ. “On the rhetorical level, the Houthis’ leadership reiterated several times their alignment with the broader Axis of Resistance.”
Gryparis’s comments, in response to a query from last week about Iran’s outreach to the Houthis, came before the Yemeni group’s embargo declaration.
“From an operational standpoint, we assess that the Houthis pose a threat and are capable of rapidly escalating,” the ASPIDES commander told us. “We maintain a frequent presence at sea, monitor the situation, and adjust our actions when needed. In the event of a resumption of Houthi attacks on merchant vessels, which remains a possibility, we are present and ready to implement our mandate, within our means and capabilities. ASPIDES remains ready, within its defensive mandate, to adapt to evolving operational requirements.”
Being drawn into defending against a new Houthi campaign on shipping in the Red Sea region would exacerbate the strain on U.S. forces already under tremendous pressure from Iran. In addition to defending against ongoing barrages, the U.S. has committed about 20 U.S. warships, along with hundreds of aircraft dispersed across various bases, vessels, and forward arming and refueling points in the Middle East, to maintaining the newly reimposed blockade on Iranian ports. Moving these assets to another prologned shooting match in the Red Sea would degrade those capabilities and the ability to support a war effort should it fully erupt. It’s a capacity issue.
Expanding the fight against Iran is already in discussion by the Trump administration.
“The U.S. is planning for a wider war,” a U.S. official familiar with internal administration discussions told The Washington Post.
But the official cautioned that “the expansion of U.S. operations will be limited by dwindling stockpiles of air defense and long-range munitions and constraints on the ability to surge more troops and aircraft into the area because of battle damage,” the newspaper continued.
“We do not have enough to safely sustain operations, and I don’t think the White House is aware of that,” the Post said the official added.
While we cannot independently confirm this latest Post report about internal administration debates, we have frequently highlighted concerns over U.S. stocks of these munitions and the difficulty in replacing them.
All this comes as there are increasing signs of damage at U.S. facilities in the Middle East from Iranian barrages. Though largely spared in the initial phases of Epic Fury due to robust air defenses, the airfield at Muwaffaq Salti Air Base in Jordan has taken the brunt of recent attacks, while several other installations have been hit as well.
Muwaffaq Salti, as we have frequently reported, has come under attack numerous times. In March, CNN obtained imagery from Planet Labs showing an AN/TPY-2 radar damaged, or even possibly destroyed, following an Iranian attack there.
The air base has long been a major regional hub for U.S. operations, and is being very actively utilized in the current conflict. It hosts the greatest concentration of U.S. tactical aircraft in the region, and thus is an extremely important target, where, as we pointed out, even one ballistic missile landing on an apron could destroy multiple prized aircraft and take the lives of U.S. service members or cause injuries.
Satellite imagery has emerged on social media purporting to show the extent of the damage at MSAB. The following shows what is claimed to be before and after views of strikes on aircraft hangars and containerized housing units. The imagery is provided by Iran and, because U.S. satellite firms do not collect over American facilities, we cannot independently confirm what is being depicted.
Beyond damage, the number of troops killed and injured in Iranian attacks is rising. On Monday, the Pentagon identified two soldiers killed in action.
“1st Lt. Tyler James Feehan, 25, of Ewa Beach, Hawaii, was killed in action on July 18, 2026, and Pvt. Isabella Gonzales, 19, of Carrollton, Texas, was killed in action on July 17, 2026, during an enemy attack on July 17, 2026, at Muwaffaq Salti Air Base, Jordan,” the Pentagon said in a statement. “The incident is under investigation.”
Both soldiers worked for air defense units. Feehan was assigned to 2nd Battalion, 55th Air Defense Artillery Regiment, 32nd Army Air Missile Defense Command, Fort Bragg, North Carolina. Gonzales was assigned to 1st Battalion, 57th Air Defense Artillery Regiment, 52nd Air Defense Artillery Brigade, 10th Army Air Missile Defense Command, Ansbach, Germany.
Today’s identifications came after CENTCOM on Saturday reported that two U.S. service members in Jordan were killed in action on July 17. Additionally, the command said one service member was currently missing, but later said unidentified remains were found.
CENTCOM also reported on Sunday that “a U.S. service member in northern Iraq was killed in action July 18 during a controlled detonation of unexploded ordnance from a downed Iranian one-way attack drone. A second service member was wounded and continues to receive medical treatment for a minor injury.”
We have asked CENTCOM and the Army to confirm that Feehan was the soldier killed in Iraq during the controlled detonation or if he was killed in another incident.
It should be noted that in announcing the identities of Feehan and Gonzales, the Pentagon said they died in support of Operation Inherent Resolve (OIR), which is the fight against ISIS in Iraq and Syria. We asked the Pentagon for clarity and they deferred us to CENTCOM, which has yet to respond.
Meanwhile, The New York Times accused the Pentagon of hiding the number of injured troops.
“In the week leading up to the Iranian attack on Friday that killed two U.S. soldiers and left one service member missing in Jordan, Iran carried out three other strikes against U.S. forces in the country,” the paper explained. “Those attacks injured dozens of U.S. service members and damaged several helicopters, according to several U.S. officials, who spoke on the condition of anonymity to discuss operational matters. But the Pentagon did not disclose the earlier strikes, nor the casualties and damage they inflicted.”
The episode “is the latest example during the Iran conflict of the tension between what the Pentagon says is the need for operational security and the government’s obligation to inform the public about the conduct of the war,” the Times proffered.
The Pentagon pushed back on that claim, rejecting it as “baseless and malicious.”
Still, despite the increasing violence, both the U.S. and Iran have suggested that further diplomacy to end the fighting is possible. This is even as both sides declared the ceasefire over and Iranians last week said they would no longer negotiate a Memorandum of Understanding on a possible peace deal.
“You can’t have an MOU that’s alive if they’re violating the terms,” U.S. Secretary of State Marco Rubio told reporters. “The U.S. always remains open to a diplomatic solution. We’ve tried multiple times with Iran and we’ll continue to try… but their behavior is what we’re responding to — and their behavior is they’re launching missiles and drones against ships.”
“Proposals were put forward by the mediators, we were informed of them, and we received them,” Iran’s Foreign Ministry spokesman Esmail Baghaei said during a press conference. “However, let me not go into details right now. The gist of the matter is that the diplomatic mission has been actively working these days, and some ideas from a number of mediators have reached us—yes, this is confirmed.”
Still, Trump threatened to continue striking Iran should more U.S. forces be killed.
“Every time Iran kills an American Soldier they will pay for that killing many times over!” the president proclaimed on Truth Social. “This directive has been passed on to Secretary of War, Pete Hegseth, Chairman of the Joint Chiefs of Staff, Daniel Caine, and every Leader in the Military.”
There are no new peace talks scheduled and it remains unclear if they will be. Meanwhile, the new Houthi blockade could deeply complicate an already highly-precarious situation in the Middle East.
UPDATE: 4:50 PM EDT –
CENTCOM announced the start of the 10th consecutive day of strikes on Iranian targets.
“Today at 4 p.m. ET, U.S. forces began a new round of strikes against Iran at the Commander in Chief’s direction,” the command stated on X. “The strikes are designed to further degrade Iranian military capabilities used to attack commercial shipping in the Strait of Hormuz.”
UPDATE: 9:59 PM EDT-
CENTCOM said it concluded the strikes at 9 PM ET.
“U.S. forces struck Iranian military command centers, maritime capabilities, missile and drone launch sites, and air defense systems to degrade Iran’s ability to continue attacking commercial vessels flowing through the Strait of Hormuz,” the command stated on X. “Commercial vessel transits through the vital international maritime corridor continue. Since early May, CENTCOM forces have helped facilitate the transit of approximately 900 commercial vessels and 450 million barrels of crude oil.”
