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.

UKMTO logged six armed men boarding a tanker 136 nautical miles east of Al Mukalla on 20 August and redirecting it toward Somalia. A vessel steered toward the Somali coast reads as an attempted seizure, a distinct hazard from the stand-off strikes the same lane has seen before.

Iran's Majlis speaker received Iraq's Hormuz carve-out request in Baghdad on 19 August, a request that treats passage as Tehran's to grant. Ghalibaf's authority over that grant sits alongside the Revolutionary Guard's separate transit rules, which have moved independently of Iran's foreign ministry before.

Iraq's parliament speaker asked Iran for special consideration on Iraqi Hormuz oil exports during Ghalibaf's 19 August Baghdad visit. Iraq presses the request from a weak position: Iran's central bank is simultaneously demanding Baghdad release Iranian reserves parked in Iraqi accounts.

Switzerland's economics ministry updated the Article 21 forms governing lawful Iran money transfers on 19 August, with only the revised forms accepted from 26 August. Bern operates one of the few remaining legal Iran payment channels and has just set a hard cutover on its control point.

Japan's foreign minister said in Muscat on 20 August that Tokyo wants closer coordination with Oman on safe Hormuz and Bab el-Mandeb passage. Japan has no naval presence of its own in the strait, so it is routing the ask through the state negotiating with Iran instead.

Oman's foreign minister joined Japan's in Muscat on 20 August to call for intensified coordination on Hormuz and Bab el-Mandeb navigation. Oman also runs the mediation track with Tehran, so the appeal travels through the same channel as the negotiation.
