Houthis seize Mokha port and Red Sea islands, tightening grip on vital shipping route
Iran-backed rebels captured Yemen's strategic Red Sea port and multiple islands near the Bab el-Mandeb Strait, displacing thousands and threatening Saudi oil exports and global shipping
Iran-backed Houthi rebels seized the strategic port city of Mokha on Yemen's Red Sea coast on September 9-10, expanding their control near the vital Bab el-Mandeb Strait that channels a significant portion of global oil trade. Pro-government forces, including the Giants Brigades and Nation's Shield units, suffered casualties and withdrew south of the city. The Houthis followed with rapid seizures of Perim Island (also called Mayun) inside the Bab el-Mandeb Strait itself, and then the Greater and Lesser Hanish islands further south, consolidating control over one of the world's most critical maritime chokepoints.
The offensive escalated the conflict beyond the fragile 2022 UN-brokered ceasefire that had largely held for four years. Renewed fighting erupted in July after Saudi-led coalition forces attempted to prevent a plane carrying Houthis from landing at Sanaa airport. The current offensive has displaced over 80,000 people in two weeks and killed approximately 150 civilians, according to UN estimates and Yemeni government sources. Saudi Arabia responded by launching at least 54 coalition air strikes on Yemen and shutting down a major cross-country oil pipeline as a precautionary measure after it came under attack.
The Houthis simultaneously launched ballistic missile and drone attacks on Saudi cities, injuring at least 73 civilians. Iranian sources told Reuters that Tehran had instructed the Houthis to attack Saudi Arabia and promised additional funding and weapons, though Iran publicly denies operational control of the group. Pakistan warned Iran that its defense pact with Saudi Arabia could be activated if such attacks continued.
Yemeni government officials expressed surprise that the Saudi air force did not attempt to prevent the Mokha seizure despite its location just 80 kilometers from the critical strait. One senior military official told the Associated Press he assessed that Saudi Arabia had not received a green light from the United States for a large-scale air campaign. The Houthis' capture of Perim Island places them within roughly 20 miles of the U.S. military base in Djibouti.
How could this affect you
Traced by who's actually in the path of this — not everyone is.
Direct
If you trade or depend on oil and shipping through the Red Sea
The Houthis now control ports and islands directly within and near the Bab el-Mandeb Strait, one of the world's narrowest and most crucial shipping lanes for Saudi oil and global energy supplies. This could lead to further attacks on vessels, higher insurance costs, longer shipping routes via Suez or around Africa, and upward pressure on global oil prices—especially as Saudi Arabia already lost the alternative route through the Strait of Hormuz to Iranian interference.
Likely
If you are a U.S. military operator or policy maker focused on Middle East stability
The rapid Houthi territorial gains suggest the Yemen ceasefire has broken down into renewed full-scale civil war. The group now controls entry points to a critical strait hosting U.S. naval operations and sits 20 miles from the U.S. base in Djibouti. Escalation could force renewed U.S. military involvement in Yemen after years of relative disengagement, or require new rules of engagement for protecting shipping and regional allies.
Likely
If you work in Saudi Arabia's energy sector or invest in Saudi equities
Saudi Arabia has already shut down a major pipeline as a precaution. The loss of the Red Sea route as a reliable export corridor could force increased reliance on overland pipelines, which the Houthis and other regional groups can also target, and on more expensive or longer sea routes. Sustained Red Sea insecurity could suppress Saudi oil production and export revenue.
Likely
If you are a civilian in Yemen or a humanitarian organization
Over 80,000 people have been displaced in two weeks; 150 civilians have been killed since September 3. The collapse of the four-year ceasefire suggests a return to the brutal civil war that killed over 150,000 people and drove Yemen toward famine. Renewed fighting could accelerate humanitarian collapse across the region.
