Summary

The Houthis have rapidly advanced across significant portions of Yemen’s Tihamah coastal region, capturing around 130km of coastline within days. This move comes after a prolonged civil war and shows the resilience of the Iranian-backed rebels despite opposition from various international forces. The capture bolsters Iran's strategic influence in critical maritime areas like the Bab al-Mandab Strait, enhancing its leverage over global oil trade.

Story summary

Houthis captured the Red Sea port city of Mokha, near Bab al-Mandeb Strait, on September 10-11, 2024, after a week-long offensive. The seizure intensified fighting along Yemen’s western coast, with government forces retaliating by launching airstrikes and artillery strikes against Houthi positions. Government spokesperson Majed Abdullah al-Nazili confirmed the Houthis' control over Mokha and surrounding areas, including key roads. This move gives the Houthis strategic leverage over a crucial shipping route that handles about 25% of daily petroleum shipments worldwide. The capture also threatens to isolate Gulf oil-producing countries from their main shipping routes through Bab al-Mandeb Strait, similar to Iran's closure of the Strait of Hormuz. Yemen’s internationally recognized government is struggling to counter this advance, with civilians in Mokha fleeing to Aden for safety.

Narrative

Baraa Shaiban, a researcher and analyst at the London-based Royal United Services Institute, says the origins of the latest upsurge in fighting – the worst since a United Nations-brokered truce in 2022 - can be traced back to July, when a Houthi delegation returned from the state funeral of Iran's Supreme Leader, Ayatollah Ali Khamenei.

Claims (34 extracted, 3 hedged)

- Published The Houthis' lightning advance across the southern reaches of the Tihamah – Yemen's arid coastal plain – appears to have taken most observers by surprise. asserted

coalition → know → coast
In a matter of days, much of this has fallen to the Houthis. asserted
much → fall → Houthis
According to some estimates, the Iranian-backed rebels have captured as much as 130km (81 miles) of the country's strategically important coastline. uncertain
rebels → accord → coastline
It's the group's most impressive military coup for several years, proving that despite a civil war that has lasted 12 years, devastating Saudi air raids and attacks by American, Israeli and British forces, the Houthis remain a force to be reckoned with. asserted
Houthis → prove → forces
With their opponents stunned and demoralised, it's unlikely the Houthis will be dislodged any time soon. asserted
Houthis → stun → ?
"Now that they are there, they're going to be entrenched," Hisham al-Omeisi, senior analyst at the Brussels-based European Institute of Peace, told the BBC. asserted
Omeisi → go → BBC

it → go → them
They enjoy the backing of Iran, support that has become even more important for Tehran in the wake of the setbacks and defeats experienced by other parts of its so-called "Axis of Resistance" – Lebanese Hezbollah, Hamas in Gaza and the Assad regime in Syria. asserted
that → enjoy → Syria
"So they redirected their support to the Houthis," al-Omeisi said. asserted
Omeisi → redirect → Houthis
"And of course they need that support." asserted
they → need → support
Even though most analysts agree that it's a mistake simply to describe the Houthis as Iranian puppets, events of the past few days raise an uncomfortable new reality. asserted
events → agree → reality
Seven months after the US and Israel launched their huge, combined assault on Iran, the regime in Tehran now exerts authority over not just one, but two of the world's most important maritime passages: the Strait of Hormuz, at the mouth of the Persian Gulf, and the Bab al-Mandab, gateway to the Red Sea (and the Suez Canal). asserted
regime → launch → Sea
"Now Iran, directly and through proxies, controls two of the most strategic choke points in the Middle East and the world," says Farea al-Muslimi, a research fellow at London's Chatham House think tank, "controlling more than 35% of the fuel and oil trade globally. asserted
Muslimi → control → trade
" "This is as much leverage as a nuclear bomb," he says. asserted
he → say → bomb
If the Houthis have also taken control of several key islands in the Red Sea, including Perim - which sits in the middle of the narrowest point of the Bab al-Mandab - then the group's ability to interfere with international shipping will be greatly enhanced. asserted
ability → take → shipping
As the group's actions in the wake of Israel's war on Gaza proved, shipping in the Red Sea is highly vulnerable to Houthi missiles, drones and small attack boats. asserted
shipping → prove → missiles
"They were able to control what was going in and out of the Bab al-Mandab and up towards Suez without having these territorial gains," Yemen expert Iona Craig told BBC Radio 4's Today programme on Friday. asserted
Craig → control → Friday
"But of course now they're controlling the area immediately overlooking the Bab al-Mandab, and this gives them far more leverage. asserted
this → control → leverage
" Shipping companies are likely to be sceptical about the sincerity of a statement released on Friday afternoon, in which the Houthi military said that maritime navigation was "safe for all companies except for Saudi vessels, which have already been subject to a blockade". asserted
which → release → blockade
In their earlier attacks, the Houthis said they were only targeting vessels linked to Israel, but in fact hit ships with no such connection, including a Norwegian-flagged tanker. asserted
they → say → tanker
Craig said the Houthis may nevertheless refrain from indiscriminate attacks, fearing a repeat of Operation Rough Rider - six weeks of major US air and naval strikes in the spring of 2025. uncertain
Houthis → say → 2025
"They've already felt the wrath of the US," she said. asserted
she → feel → US
But would the US want to get involved anyway? asserted
US → want → ?
With oil prices creeping back up, it's doubtful that a new front would do much to enhance his approval ratings or his Republican party's chances in November's midterm US elections. asserted
front → creep → elections
According to the Axios website, appeals for US intervention from the Saudi Crown Prince Mohammed bin Salman have so far gone unanswered. uncertain
appeals → accord → Prince
Axios writes that the US "is increasingly concerned about the escalating conflict in Yemen and is working to intensify its support for the kingdom while simultaneously seeking to avoid direct military involvement". asserted
US → write → involvement
But it's not just the potential threat to the Bab al-Mandab that's causing fear in Saudi Arabia. asserted
that → cause → Arabia
Satellite images of an apparent Houthi missile-and-drone attack on Saudi Arabia's East-West pipeline – a vital alternative route for oil exports following the closure of the Strait of Hormuz earlier this year – point to an effort by Iran's Yemeni allies to add to the economic pressures generated by the US-Israeli war with Iran. asserted
images → follow → Iran
Even if Iran did not directly order the attack, it clearly stands to benefit. asserted
it → order → attack
Baraa Shaiban, a researcher and analyst at the London-based Royal United Services Institute, says the origins of the latest upsurge in fighting – the worst since a United Nations-brokered truce in 2022 - can be traced back to July, when a Houthi delegation returned from the state funeral of Iran's Supreme Leader, Ayatollah Ali Khamenei. asserted
delegation → base → Leader
"Immediately after, the escalation started," he says, "and it looked very clearly that [Iran was] determined to now have a bigger foothold on the Red Sea". asserted
Iran → start → Sea
With Yemen teetering on the edge of a return to all-out war, Saudi Arabia anxious about preserving its economic lifeline to the Red Sea and Donald Trump apparently reluctant to get involved, America's conflict with Iran just took on a new and potentially dangerous dimension. asserted
conflict → teeter → dimension
For the people of Yemen, displaced, bombed, starved and impoverished by a dozen years of civil war, recent developments can only make their lives worse. asserted
lives → displace → war
