Houthis join Iran war fight, threatening Red Sea shipping amid Hormuz closure

Houthis Join Iran's War Effort, Escalating Threats to Red Sea and Gulf Shipping

Houthis join Iran war fight threatening - The Houthi rebels in Yemen have aligned themselves with Iran in the ongoing conflict, launching a missile strike against Israel on Monday. This move has intensified concerns over the safety of maritime trade routes, as the rebels have declared a ban on Israeli vessels in the Red Sea. The blockade extends beyond the Red Sea, placing the critical Gulf of Aden and the narrow Bab el-Mandeb Strait—linking the two bodies of water—under potential threat. These strategic chokepoints are vital for global commerce, with the Bab el-Mandeb Strait serving as a key passage for nearly 12% of the world’s maritime trade.

Following the Israel-Hamas war in Gaza, the Houthis intensified their attacks on commercial ships passing through the vital seaway. During the conflict, they launched around 200 strikes, disrupting the flow of goods worth approximately $1 trillion (€866bn) annually. This disruption forced shipping companies to adopt a detour around the southern tip of Africa, adding about 14 days to transit times and increasing operational costs significantly. The economic impact was stark, as oil shipments through the Bab el-Mandeb Strait plummeted from 8.8 million to 4 million barrels per day during the campaign. This decline highlights the strategic importance of the region for energy exports.

The current escalation comes as the Strait of Hormuz, the gateway to the Gulf and its energy producers, remains under Iranian control. The waterway, which carries approximately one-fifth of the world’s seaborne oil and gas, has been a focal point of the war, with Tehran using it as a strategic tool to pressure global markets. The Houthis’ renewed threat adds another layer of tension, as the rebels have vowed to continue targeting Israeli shipping if the Iran war intensifies. This declaration follows a brief pause in their attacks after the Gaza ceasefire was announced in October 2025.

Historically, the Houthis have been active in the Red Sea, leveraging their control of the region to disrupt international trade. Their operations have targeted both commercial and military vessels, with the latest attack marking a significant escalation. The rebels, formally known as Ansar Allah, have held much of Yemen for over a decade after seizing the capital, Sanaa, in September 2014. This long-standing conflict has seen them develop a network of support from Iran, which has provided them with military training and resources.

The recent missile barrage is part of a broader strategy by the Houthi group to assert control over critical maritime corridors. Their statement from the armed forces emphasized a complete prohibition on Israeli navigation within the Red Sea, stating, “We consider all enemy movements to be legitimate military targets for our armed forces from the moment this statement is issued.” This bold assertion underscores their intent to expand their influence beyond Yemen’s borders, targeting key nodes in the global supply chain.

"We declare a complete and total ban on Israeli maritime navigation in the Red Sea," said a statement from the Houthis' armed forces. "We consider all enemy movements to be legitimate military targets for our armed forces from the moment this statement is issued."

The attack coincided with renewed clashes between Israel and Iran, which placed the ceasefire under pressure. With Tehran’s continued blockage of the Strait of Hormuz, the global energy market faces further instability. The Houthi rebels, as part of the Tehran-backed Axis of Resistance, have aligned with groups such as Hezbollah in Lebanon and Hamas in Gaza. This coalition, which also includes militias from Iraq, represents a significant shift in regional dynamics, as it unites forces against Western interests in the Middle East.

The economic ramifications of the blockade are profound. The Bab el-Mandeb Strait, measuring just 26 kilometers at its narrowest, is a critical artery for trade between Asia and Europe. Any disruption here could lead to higher fuel prices and supply shortages worldwide. Meanwhile, the Strait of Hormuz, a lifeline for oil exports, remains a hotspot for geopolitical tensions. The combination of these two chokepoints under threat has raised alarms among shipping firms and energy traders alike.

Analysts warn that the situation could worsen if the Iran war continues to escalate. The Houthis’ involvement in the conflict has added a new dimension, as their attacks target not only military assets but also civilian shipping. This dual approach has created a complex web of threats, with the potential to impact both the energy sector and the global economy. The Israeli military responded to the missile strike by confirming on Telegram that they had identified the launch of a missile from Yemen toward Israeli territory, with aerial defense systems actively intercepting the threat.

Since the fragile ceasefire in Gaza began on April 8, the Houthis have been relatively restrained in their attacks. However, their recent actions signal a return to aggressive tactics, likely in response to the Iran war’s intensification. This move has not only reignited fears of a regional conflict but also highlighted the interconnectedness of Middle Eastern tensions. The rebels’ decision to join the Iran war has transformed the Red Sea into a battleground for international trade, with implications stretching far beyond the immediate region.

As the world watches the situation unfold, the stakes for maritime security have never been higher. The combination of the Houthi rebels’ assertiveness and Iran’s continued dominance over the Strait of Hormuz could lead to a prolonged disruption of global shipping networks. This scenario poses a challenge for nations reliant on these routes, as they scramble to find alternative pathways and secure their economic interests. The potential for further escalation remains a key concern, with the Red Sea and Gulf of Aden now central to the geopolitical landscape of the Middle East.
