Yemen’s Houthi movement has launched a major new offensive aimed at expanding its territorial control, particularly along the western coastline.
In recent fighting, the group reportedly captured the strategic port city of Mocha (Al-Mukha) and several nearby areas that form a vital link between the Red Sea coast, the Bab al-Mandab Strait, and the Gulf of Aden.
Mocha had long been under the control of forces aligned with Yemen’s internationally recognized government and its allies.
The latest battles reportedly forced the withdrawal of the National Resistance Forces (NRF), led by Tareq Saleh, giving the Houthis control of one of the most strategically important locations on Yemen’s Red Sea coast.
The city lies approximately 60 to 75 kilometers from the Bab al-Mandab Strait, placing the group closer than ever to one of the world’s most important maritime chokepoints.
The Houthis have also advanced into other coastal districts, including Hays and Al-Khawkhah. Control of these areas strengthens the land corridor between Hodeidah, already a major Houthi stronghold, and Mocha.
Analysts warn that the gains could allow the group to establish a nearly continuous zone of influence along much of Yemen’s western coastline, increasing its leverage over maritime routes near the Bab al-Mandab Strait.
The fighting has also drawn attention to several strategically important islands in the Red Sea, including Perim (Mayyun), the Hanish Islands, and Zuqar Island. Perim Island is particularly significant because it sits directly within the Bab al-Mandab Strait.
Any force that controls or exerts influence over the island gains a valuable position for monitoring and potentially disrupting maritime traffic moving between the Red Sea and the Gulf of Aden.
The offensive comes amid heightened tensions across the Middle East.
The Houthis, who maintain close political and military ties with Iran, have repeatedly aligned themselves with regional actors opposed to the United States and Israel.
At the same time, Yemen’s internationally recognized government and the Saudi-led coalition have intensified military operations in an effort to contain further Houthi advances.
The Bab al-Mandab Strait is the primary reason why developments in western Yemen attract global attention.
Located between Yemen and the Horn of Africa—particularly Djibouti and Eritrea—the waterway connects the Gulf of Aden to the Red Sea and serves as a gateway to the Suez Canal.
Djibouti lies roughly 30 kilometers from the strait, while Eritrea’s coastline is also located nearby, underscoring the region’s strategic importance.
Despite the recent gains, Yemen remains divided. The Houthis control large portions of northern and western Yemen, including Sana’a and Hodeidah, while the internationally recognized government and its allies retain important territories such as Aden, Marib, parts of Taiz, Lahij, Shabwa, and Hadramout.
The capture of Mocha and surrounding areas would represent one of the most significant setbacks for the Saudi-backed coalition in recent years.
The importance of Bab al-Mandab extends far beyond Yemen’s borders.
A substantial share of global trade, including oil, liquefied natural gas, and manufactured goods, passes through the strait on its journey between Asia, Europe, and the Mediterranean via the Red Sea and the Suez Canal.
If shipping companies conclude that the route has become too dangerous, vessels may be forced to reroute around the Cape of Good Hope at the southern tip of Africa.
Such a detour adds thousands of kilometers to voyages, increases fuel consumption, delays deliveries, raises insurance costs, and can ultimately drive up global prices for energy and consumer goods.
For that reason, the battle for Yemen’s western coast is not simply a local conflict. It is a struggle taking place near one of the world’s most critical trade arteries.
Any significant shift in control around Bab al-Mandab could have consequences for regional security, international shipping, global supply chains, and the broader balance of power in the Middle East and the Horn of Africa.
