Houthis open new front in Iran war, global shipping at risk

The Iran war has widened dramatically after Yemen’s Houthi movement announced it was joining the fight on Tehran’s side, launching missiles at Israel and threatening shipping in the Red Sea.

The move places two of the world’s most strategically important maritime chokepoints under simultaneous pressure. With Iran already maintaining a blockade of the Strait of Hormuz, the renewed Houthi threat now puts the Red Sea, Gulf of Aden and Bab el-Mandeb Strait firmly in the firing line.

Red Sea Trade Route Back Under Threat

The Houthis declared a “complete and total ban” on Israeli maritime navigation in the Red Sea, warning that vessels linked to Israel would be considered legitimate military targets.

The threat revives fears of a repeat of the disruption seen during the Gaza war, when Houthi attacks forced major shipping firms to abandon the Red Sea route. Hundreds of vessels were diverted around southern Africa, adding weeks to journeys between Asia and Europe and driving up transport costs across global supply chains.

Two Chokepoints, One Growing Crisis

The timing is especially significant. The Bab el-Mandeb Strait carries roughly 12% of global maritime trade and serves as the gateway between the Red Sea and the Indian Ocean.

At the same time, the Strait of Hormuz remains under pressure from the wider conflict. Together, the two waterways handle a huge share of global energy and commercial traffic. Any prolonged disruption could ripple through oil markets, freight networks and consumer prices worldwide.

Missiles Fly as Ceasefire Wobbles

The Houthis also claimed responsibility for a missile barrage against Israeli targets, saying the strikes achieved their objectives. Israel confirmed a missile launch from Yemen and said air defence systems were activated to intercept the threat.

The attack marks a sharp escalation after months of relative restraint and comes as Israel and Iran continue exchanging fire, placing an already fragile ceasefire under renewed strain.

Axis of Resistance Mobilises

The Houthis form part of Iran’s so-called Axis of Resistance, alongside Hezbollah, Hamas and allied militias across the region.

Their entry into the conflict increases the risk that a war once centred on Israel and Iran could spread across multiple fronts. With key trade routes under threat and regional proxies mobilising, the economic and security consequences are rapidly becoming global.
