A group of rebels once known as Iran's "merchants of chaos" have moved on strategic islands in the Red Sea and are now putting one of the richest and most powerful nations in the Middle East in a tricky spot.
asserted
group → know → spot
After a years-long stalemate, the Houthis reignited their war with Saudi Arabia and the internationally recognised government this year, launching a lightning assault in mid-September that ended in the capture of Mokha, a major port city, and the tiny island of Perim.
asserted
that → reignite → Perim
The seizure of the two critical areas gave the Houthis almost complete control of Yemen's Red Sea coastline, and put them within firing distance of any ships that attempted to navigate the Bab el-Mandeb Strait.
asserted
that → give → Strait
(The Houthis had announced a blockade of ships carrying Saudi Arabian exports in July.)
asserted
Houthis → announce → July
"By taking the territory this simply allows [the Houthis] to harass shipping more easily and it also establishes them as the powerbroker in this critical waterway," said April Longley Alley, a Middle East analyst with the Washington Institute.
asserted
Alley → take → Institute
The Iran-aligned group were quick to act on their strategic advantage, firing at Saudi oil facilities on September 8 and tankers that attempted to navigate the narrow strait.

Houthis → begin → Arabia
Fuel tanks near the Saudi capital's international airport were targeted, as well as energy sites on the country's Red Sea coast.
asserted
tanks → target → coast
Unlike many other nations, Saudi Arabia escaped the initial months of the war between Iran and the United States relatively unscathed.
asserted
Arabia → escape → Iran
But analysts now fear the Houthis' growing assertiveness in the region could open a new, troubling front in the Middle Eastern conflict.
uncertain
assertiveness → fear → conflict
"It's monumental because Saudi Arabia was spared, and today Saudi Arabia will not be spared if the Houthis in Yemen are not reined in," Dr John Sfakianakis, chief economist at the Gulf Research Center in Riyadh, told ABC Radio.
asserted
Sfakianakis → spar → Radio
Analysts warn the rebel group's actions in the Bab el-Mandeb Strait could also have a very real, and very troubling, impact on the prices consumers pay for oil and gas.
uncertain
consumers → warn → oil
"It is damaging for everybody and nobody is spared from this," Dr Sfakianakis said.
asserted
Sfakianakis → spar → this
As fighting has escalated in recent weeks, the Saudis looked to their allies, the United States, to intervene, as it did previously under the Biden administration and last year under Trump.
asserted
it → escalate → Trump
Crown Prince Mohammed bin Salman, the kingdom’s de facto leader and a major ally in the Iran war, even reportedly called the US President on September 17 to implore him for US assistance.
uncertain
Salman → call → assistance
Over the weekend, Donald Trump came close to heeding those calls and ordering military strikes against the Houthis.
asserted
Trump → come → Houthis
Military commanders were locked and loaded, holding approved target lists as troops loaded bombs onto aircraft selected for the operation, the New York Times reported.
But the planned strikes were called off at the 11th hour, according to the newspaper, with Mr Trump deciding there would be no US action "for now".
uncertain
Trump → lock → newspaper

The Bab el-Mandeb Strait, known in Arabic as the Gate of Tears, sits between the Horn of Africa and the Middle East, and is the gateway to the Red Sea.
asserted
Strait → know → Sea
For millennia, this inlet facilitated local trade between Arabia and Africa, before expanding to international trade with the opening of the Suez Canal in 1869.
asserted
inlet → facilitate → 1869
The narrow waterway now connects many of the Middle East's oil and commodity producers to the rest of the world, making it one of the busiest global maritime chokepoints.
asserted
it → connect → chokepoints
When Iran moved on the Strait of Hormuz earlier this year, it exposed a key vulnerability in global shipping and forced many nations to look for alternate routes for their cargo.
The Bab el-Mandeb Strait became a "Plan B" export route during the Iran war, helping to cushion the impact of the effective closure of the Strait of Hormuz, particularly when it came to the oil-rich Saudi Arabia.
The kingdom started diverting a large amount of its exports away from the Strait of Hormuz into the East-West pipeline.
asserted
kingdom → move → pipeline
Built in the early 1980s, the 1,200 kilometre pipeline connects Saudi Arabia's Abqaiq oil processing facility in the east to the Red Sea port of Yanbu in the west.
asserted
pipeline → build → west
From there, Saudi oil, which is mostly bound for Asia, is loaded onto tankers and carried out via two routes in the Red Sea.
asserted
which → bind → Sea
"During the course of the Iran war, Saudi Arabia has become more dependent on the Red Sea for the export of hydrocarbons they've exported through their East-West pipeline, through the port of Yanbu on the Red Sea coast," Ms Longley Alley said.
asserted
Alley → become → coast
"And so the Houthis see an opportunity again to press their advantage with Saudi Arabia and to see if they get into war …on their terms."
asserted
they → see → terms
Under the law of the sea, freedom of navigation in the world's strategic shipping channels is guaranteed.
asserted
freedom → guarantee → channels
That is how the Bab el-Mandeb Strait is supposed to operate.
asserted
Strait → suppose → ?
But just like with the Strait of Hormuz, this narrow passageway now appears to be beyond the bounds of international law.
asserted
passageway → appear → law
"One of the things [the Houthis] demonstrated to the world, in effect almost teaching Iran or demonstrating to Iran, was that with the use of relatively cheap, relatively unsophisticated technology and weaponry … just the threat of that alone is enough to stop shipping," Timothy Walker, maritime researcher at the Institute for Security Studies in South Africa, told RN's Rear Vision.
asserted
Walker → demonstrate → Vision
During Israel's war with Gaza, the Houthis paralysed shipping through the Red Sea, killing at least nine sailors and sinking four ships.

Houthis → paralyse → ships
Barrels of crude oil and petroleum liquids crossing the strait per day dropped from 9 million in 2023 to about 4.2 million barrels in 2025.

The US launched a bombing campaign against the Houthis in response and the two sides eventually reached a ceasefire deal, brokered by Oman, last year.
asserted
sides → launch → Oman
This time, the Houthis claim their actions in the Bab el-Mandeb Strait are a result of Saudi Arabia's own "unjust blockade on shipping traffic to and from Yemen".
uncertain
actions → claim → Yemen
The Houthis' endgame is complex and multifaceted but analysts said one of the group's desires is to see the end of all Saudi involvement or intervention in Yemen, including the kingdom's backing of the internationally recognised government.
asserted
one → say → government
"Saudi arrogance is unacceptable and the Saudi regime is an occupying power," Houthi leader Abdul Malik al-Houthi said in a televised speech on Monday.
asserted
Houthi → occupy → Monday
Their actions also give Iran, which provides the Houthis with military support, another potential source of leverage as the United States loosens Tehran's grip on the Strait of Hormuz, on the other side of the Arabian Peninsula.
asserted
States → give → Peninsula
Analysts said renewed hostility in the Bab el-Mandeb Strait would very likely disrupt exports again, making it more difficult to get oil from the west coast of Saudi Arabia to Asia and Australia.
asserted
it → say → Asia
They warn that simply having the threat of disruption is very powerful because insurance companies become nervous about sending ships through the area and into harm's way.
asserted
companies → warn → way
