Houthis Seize Full Control of Yemen's Red Sea Coast, Threatening Key Global Shipping Route

Iran-aligned Houthi forces have taken control of Yemen's entire Red Sea coastline, including the strategic Perim Island and the Bab al-Mandeb strait, in a ten-day blitz that has given Tehran effective dominance over one of the world's most critical shipping chokepoints. The rapid offensive, which began on September 3 with heavy fighting against Saudi-backed Yemeni government forces, has displaced at least 46,000 people and prompted Saudi Arabia to prepare what officials describe as a major sea and possible land counter-offensive.

The Houthis now control the entire western coastline stretching from the Saudi border in the north to the Bab al-Mandeb strait in the south, a narrow passage that links the Gulf of Aden with the Red Sea and handles roughly 10 percent of global seaborne oil shipments. Military analysts say the advance consolidates Houthi leverage over the shipping route at a time when the spillover from the six-month US-Iran war has already disrupted maritime traffic and sent insurance premiums soaring for vessels transiting the region.

A Yemeni military official told AFP that government forces offered little resistance as the Houthis swept through coastal towns including Mokha and Zabid, seizing the strategically located al-Omari military camp and key infrastructure previously held by Saudi-backed troops. Blame for the collapse has been directed at Yemeni government leaders, the United States, and Saudi Arabia, all of whom critics say failed to coordinate an effective defense despite clear signs that the Houthis were massing forces for a coordinated assault.

The offensive breaks a fragile ceasefire that had largely held since 2022, when the Houthis and the internationally recognized Yemeni government agreed to suspend major combat operations. The resumption of large-scale fighting is widely viewed as a spillover effect of the broader US-Iran conflict, which has drawn in regional proxies and destabilized fragile truces across the Middle East. The Houthis have framed their advance as a defensive measure against what they describe as Western-backed aggression, though their control over the Red Sea coast serves Iran's strategic interest in projecting power across critical maritime corridors.

On September 13, the Houthis claimed to have struck a Saudi military base with ballistic missiles in retaliation for Saudi airstrikes that targeted Houthi positions along the newly captured coast. The exchange of fire signals that Saudi Arabia is preparing to launch a counter-offensive aimed at dislodging the Houthis from the Red Sea littoral, though Riyadh has not publicly announced the scale or timeline of such an operation. The Guardian reported on September 10 that Saudi forces were mobilizing for a sea and possible land offensive, raising the prospect of a renewed Saudi military intervention in Yemen's grinding civil war.

The United Nations envoy to Yemen warned that the risk of large-scale war has become a "harsh reality" and called for immediate de-escalation. However, the strategic value of the territory seized by the Houthis makes a negotiated withdrawal unlikely without significant pressure or military reverses. Control over the Bab al-Mandeb strait gives the Houthis the ability to threaten or disrupt shipping at will, a capability that amplifies Iran's regional influence and complicates efforts by the United States and its allies to secure maritime trade routes.

The Houthi advance has also reignited debate over the effectiveness of the Saudi-led coalition's military strategy in Yemen. After nearly a decade of intervention, Saudi Arabia has failed to dislodge the Houthis from northern Yemen or prevent them from threatening Saudi territory with cross-border missile and drone strikes. The latest offensive highlights the coalition's inability to maintain control over territory it had previously secured, raising questions about whether Saudi Arabia has the political will or military capacity to reverse the Houthis' gains.

The International Organization for Migration reported that 46,000 people have fled the fighting since September 3, with many seeking refuge in Djibouti across the Bab al-Mandeb strait. The displacement adds to Yemen's already catastrophic humanitarian crisis, which has left millions dependent on international aid and exposed to disease, malnutrition, and violence. Humanitarian agencies have warned that renewed fighting could further restrict access to aid and worsen conditions for civilians trapped in conflict zones.

The Houthi offensive also complicates efforts to broker a broader peace settlement in Yemen. The 2022 ceasefire had raised hopes that the civil war, which began in 2014 when Houthi forces seized the capital Sanaa, could be resolved through negotiations brokered by the United Nations and regional powers. However, the Houthis' decision to launch a major offensive suggests they believe military gains will strengthen their negotiating position or that they no longer see diplomatic engagement as a viable path to securing their objectives.

For global shipping companies, the Houthi takeover of Yemen's Red Sea coast adds another layer of uncertainty to an already volatile region. The strait of Bab al-Mandeb is one of the world's busiest maritime passages, and any prolonged disruption could force tankers and container ships to reroute around the southern tip of Africa, adding weeks to transit times and billions of dollars in costs. Insurers have already raised premiums for vessels transiting the Red Sea and Gulf of Aden, and the Houthi advance is likely to push those costs higher as the risk of attacks or blockades increases.
