Key takeaway

A second Houthi barrage in 24 hours confirms Iran's proxy network is activating in sequence.

The Houthis (Ansar Allah) fired their second missile and drone barrage at Israel on 29 March, following their first attack the previous day . Israeli military claimed interceptions; targets included what the Houthis described as "sensitive military sites" in southern Israel ¹. Deputy information minister Mohammed Mansour has explicitly threatened Bab al-Mandeb closure as part of a staged escalation programme.

Tehran coordinated the timing. Houthi entry came the day after Pakistan confirmed US-Iran indirect talks had stalled and the day Iran published its five conditions . Two attacks in 24 hours is a demonstration of sustainable tempo, not a one-off provocation. The Long War Journal reports that Houthi leaders have conditioned further escalation on whether other nations join anti-Iran operations or use the Red Sea for strikes against Iran's allies.

The strategic problem is compounding. Hezbollah fired 600 projectiles at Israel on 28 March . The Houthis are now adding a second axis. Iran's proxy network is activating in sequence, each front requiring separate defensive resources from a coalition already stretched by the primary conflict.

Deep Analysis

In plain English

Yemen's Houthi movement, which controls most of northern Yemen including the Red Sea coast, is an Iranian-aligned armed group. On 28 March it fired its first missiles at Israel. Within 24 hours it fired a second wave. This matters because the Houthis also control the Bab al-Mandeb strait, the other end of the Red Sea from Hormuz. They have now explicitly threatened to close it. The situation in brief: Iran controls one end of the Gulf-to-Red Sea shipping corridor through Hormuz. Its Houthi allies may be about to close the other end at Bab al-Mandeb.

Deep Analysis

Root Causes

The Houthi activation followed Pakistan's confirmation that indirect US-Iran talks had stalled. Tehran appears to have calibrated proxy activation against the diplomacy clock: when talks collapsed, the proxy network activated. This suggests a deliberate coercive strategy rather than autonomous Houthi decision-making.

The Houthis have their own motivations that partially overlap with Tehran's. Bab al-Mandeb closure would be the single largest expression of Houthi strategic power and a recruiting and fundraising windfall domestically in Yemen.

Qatar

Primary parallel: Hezbollah's 2006 rocket campaign against northern Israel opened a second front that stretched IDF resources during the Lebanon War. Like the current Houthi activation, it began with limited salvoes that escalated in frequency.

Counter-parallel: In 2006, Hezbollah operated from contiguous territory with a resupply corridor; IDF could conduct ground operations to degrade launch capability. Yemen's geographic distance from Israel significantly constrains Israeli retaliation options.

Consensus view: The Long War Journal and the Middle East Eye assess the Houthi tempo shift from sporadic attacks to two barrages in 24 hours as a demonstration of sustainable operational capability, not a one-off escalation designed to signal and de-escalate.

Counter-view: Iranian opposition media Iran International argues the Houthi activation is more controlled than it appears: Tehran is deploying the proxy network sequentially to maximise pressure without triggering a direct escalation that would force the US to respond against Yemen as a third theatre.

Key tension: Whether the Houthis can sustain two-barrage-per-day tempo against Israeli air defences, or whether the first failed interception attempts will produce Israeli retaliation against Houthi launch sites that draws the US in.

Different Perspectives

Spain's LNG terminal operators

Spain's 9,145 GWh terminal inventory is the largest single stock in the EU LNG network, an option value that can reroute cargoes wherever the winter strip pays best rather than a cavern gas obligation tied to a fixed date. That flexibility matters more as Germany's cavern shortfall pushes more of the winter security question onto import infrastructure.

European Commission

Brussels holds the bloc to 90% on a flexible window while Germany, holding roughly a quarter of EU storage capacity, tracks toward missing its own lower 80% figure by 21 points. A national shortfall this size in the anchor market matters more to bloc security than the flexible timetable alone can absorb.

French power exporters and CRE

French day-ahead rose in step with Germany but by less, reopening a EUR 7-17 premium that makes northward export flows commercially attractive again after the EUR 43.09 discount evaporated in days. CRE separately authorised RTE and Enedis to buy flexibility locally, betting the coming winter's binding constraint is grid congestion rather than a shortage of firm capacity.

TTF trading desk

A visible national shortfall like Germany's 21-point gap is a directional signal, not noise, for a desk holding the summer-winter spread. TTF's flat EUR 58-60 range through this week's German price swings says the market has not yet chosen to reprice refill risk into the front of the curve.

German cavern and CCGT operators

German caverns kept buying prompt gas at TTF near EUR 58-60 through the inversion; the wind collapse to 2.4 GW then flipped the spark spread to plus EUR 29 and put turbines back in the same queue. Every day turbines win that bid, injection at a third of the 877 GWh/day pace needed falls further behind.

Slovakia

Slovakia says it dropped its hold-out on the 21st sanctions package only after Ursula von der Leyen personally signed written gas-price and supply guarantees. The Council of the European Union's own 17,238-character release on the package names neither Slovakia nor any guarantee, leaving Bratislava's account unconfirmed by the institutional record.
