Iran-backed Houthi rebels struck Yemen’s Red Sea coastline and claimed an attack on Saudi Arabia’s oil infrastructure as regional shipping risks sharpened, according to reporting citing medical and military sources. On Sunday, strikes in the port city of Mokha killed at least 11 people, a medical source said, after an earlier drone salvo targeted a Saudi oil refinery.
The toll in Mokha was described by the Aden-based government—Yemen’s internationally recognised administration—as three civilians and eight military personnel killed in Houthi attacks. The information was attributed to a medical source located in Mokha, an area under the government’s control, underscoring the human cost of the renewed campaign along a strategic maritime corridor.
Beyond Mokha, the attacks were described as broader than a single location. One of two military sources said the Houthis also hit pro-government forces and installations outside the city, as well as positions on islands near Bab al-Mandab, the narrow strait that forms the southern gateway to the Red Sea. Bab al-Mandab is also a critical funnel for shipping heading toward major ports and energy routes.
While the Houthis were reported to have targeted some sites where Saudi troops were believed to be present, the same military source said there were no reported casualties among personnel from Saudi Arabia. The account suggests the operations may have been designed to pressure Saudi-linked logistics and regional posture while avoiding direct escalation involving Gulf forces, even as the wider campaign appears to broaden.
The reporting also connected the renewed attacks to a breakdown of a UN-backed 2022 accord. In parallel with strikes on the ground and at sea, the rebels announced a maritime blockade of Saudi Arabia. That measure, the reports said, included actions against Saudi tankers in the Red Sea and the kingdom’s oil infrastructure.
The Houthi moves come amid heightened attention to chokepoints across the region. In the same period, Iran’s actions have been described as creating a similar effect on the Strait of Hormuz, the gateway to global oil supplies. With Hormuz effectively shut by Iran in this reporting context, the Red Sea and Bab al-Mandeb have regained prominence as alternate routes—particularly for Saudi Arabia’s oil shipments—potentially amplifying the consequences of any interdiction campaign.
Escalation is not confined to refinery claims and strikes onshore. The wider Red Sea threat has also featured direct attacks on vessels navigating the Bab el-Mandeb Strait. In a separate account attributed to the Associated Press, crew members of a Yemeni commercial ship described how a second missile struck as rescue efforts were underway after an earlier strike, worsening casualties and chaos for survivors. Greenwich Time reported that three ballistic missiles fired by the Iran-backed Houthis hit the ship off Yemen’s coast near the strait, killing six people and injuring at least nine, according to Yemeni authorities.
That AP-linked reporting framed the campaign as part of an escalating pattern, highlighting the economic stakes of the maritime route. Bab el-Mandeb connects the Red Sea to the Gulf of Aden and accounts for roughly 12% of global trade, meaning even short disruptions can have outsized impacts on timelines and costs for shipping and energy delivery. The crew member quoted described the scene as “doomsday,” capturing the suddenness with which attacks can overwhelm port operations.
Attacks linked to the conflict have also extended to ships associated with support for Yemen’s government. On August 11, another report said a small cargo ship tied to Yemen’s government was struck—possibly in multiple attacks—after departing Mokha. The Maritime Executive reported that the government initially said three crewmembers died, later revising the figure to four as additional injuries and information emerged.
According to that same account, the Yemen Ministry of Transport described the vessel as a Yemeni ship, while the Iranian news agency Mehr reported it was associated with Saudi Arabia. Unconfirmed reports suggested the cargo may have included military supplies for the government backed by Saudi Arabia. The report also indicated the fourth death may have involved a member of the Yemen Coast Guard and that three others were injured, with the series of attacks spanning Sunday and into Monday.
Strategically, the latest developments illustrate how the Houthis appear to be applying pressure on multiple fronts: direct strikes on Yemen’s port and installations, drone salvos aimed at Saudi energy targets, and maritime operations that threaten the movement of shipping through the Red Sea. The combined effect is likely to strain civilian and commercial logistics while increasing the risk of further incidents at sea.
Internationally, officials and regional actors have continued to tie the unfolding situation to broader regional dynamics. Coverage highlighted that Iran’s foreign minister reiterated Tehran’s stance against reopening the Strait of Hormuz until the United States meets specified conditions, while U.S. President Donald Trump was described as seeking compensation from Iran “for all of the people that they have killed” in the past. In that context, focus has shifted further to Yemen’s Red Sea ports and alternate shipping routes through Bab el-Mandeb. Fortune described the Mokha strikes and other assaults as part of an escalation by the Houthis against government forces and oil facilities in neighboring Saudi Arabia that supports Yemen’s internationally recognised government.
For now, officials and witnesses continue to assess damage and casualties as attacks ripple through both Yemen and the surrounding waters. The Houthi claims of striking a Saudi refinery, coupled with announcements of a maritime blockade, raise the prospect that the Red Sea—already vital to energy transport—could see further disruption. With Bab al-Mandab serving as a narrow and high-traffic gateway, every incident risks prompting rapid changes in routing decisions, insurance costs, and security calculations for ships operating in the region.
