Key takeaway

Iran activated the Houthis after talks collapsed, threatening a second chokepoint.

Ansar Allah fired a barrage of ballistic missiles at military sites in southern Israel on 28 March, their first attack since the war began on 28 February. 1 The IDF intercepted one missile; sirens sounded in Beersheba.

Houthi military spokesman Brigadier-General Yahya Saree announced the strikes via Al Masirah TV and stated they would continue "until the aggression against all fronts of the resistance ceases." 2 The Houthis had sat out the war's first four weeks at Tehran's request. Their entry is a reversal, and its timing is deliberate: it came the day after Pakistan confirmed indirect US-Iran talks had stalled and the day Iran published five conditions for ending the war, including sovereignty over the Strait of Hormuz .

Tehran chose this moment to activate the proxy it had held in reserve. The military threat from a single intercepted missile is secondary. The strategic threat is geographic: combined with Iran's existing traffic control at Hormuz, where only five vessels crossed on 25 March , two of the world's three critical maritime chokepoints are now contested simultaneously for the first time since the 1973 oil crisis.

Deep Analysis

In plain English

Iran has a network of armed groups across the Middle East it funds and supplies. The Houthis, who control northern Yemen, are one of these. Since the war began on 28 February, they had stayed out of the fight at Iran's request. On 28 March they fired their first missiles at Israel. One was shot down; air raid sirens went off in the southern Israeli city of Beersheba. The Houthi spokesman said they would keep firing until all attacks on their allies stop. Why does this matter beyond one intercepted missile? Because the Houthis sit on the coast next to a second major oil shipping route called Bab al-Mandeb. Iran already controls the Strait of Hormuz. If both routes come under threat at the same time, the world's energy supply faces a problem no emergency reserve can fix.

Deep Analysis
Root Causes

The Houthis' decision calculus has two structural drivers the body does not address. First, Israeli strikes in August-September 2025 destroyed Houthi command-and-control, leaving the group with missiles but no officers who could plan integrated operations . Tehran has spent the war's first four weeks rebuilding that coordination layer, which explains the delay.

Second, the Houthis are politically incentivised to enter regardless of Iranian instructions. Sitting out a war that kills co-religionists in Gaza and Lebanon while the group claims to be the region's most committed resistance force is a legitimacy problem. Iranian restraint and Houthi domestic politics were converging toward the same outcome.

What could happen next?
  • Risk

    If the Houthis close Bab al-Mandeb, the IEA's 400 million barrel reserve release cannot compensate; two chokepoints cannot be substituted simultaneously.

    weeks · High
  • Consequence

    Houthi entry invalidates the US ceasefire framework; any deal must now cover four fronts, not two.

    days · High
  • Precedent

    Iran has demonstrated it can hold proxies in reserve then activate on diplomatic cue, making proxy networks a coercive bargaining tool rather than a standing threat.

Different Perspectives
India (BRICS meeting host, grey-market beneficiary)
India (BRICS meeting host, grey-market beneficiary)
New Delhi hosted the BRICS foreign ministers' meeting on 14 May that Araghchi attended under the Minab168 designation, giving India a front-row seat to Iran's diplomatic positioning. India's state refiners have been absorbing discounted Iranian crude through grey-market routing since April; Brent at $109.30 means every barrel sourced outside the formal market generates a structural saving.

Hengaw / Kurdish human rights monitors
Hengaw's daily reports from Iran's Kurdish provinces remain the sole independent cross-check on Iran's judicial activity during the conflict. Two executions across Qom and Karaj Central prisons on 15 May and five Kurdish detentions on 15-16 May indicate the wartime judicial pipeline is operating independently of military tempo.
Pakistan (mediator and bilateral partner)
Pakistan (mediator and bilateral partner)
Islamabad spent its diplomatic capital as the US-Iran MOU carrier to secure LNG passage for two Qatari vessels through a bilateral Pakistan-Iran agreement, spending its mediation credit for direct economic gain. China's public endorsement of Pakistan's mediatory role on 13 May is the structural reward.

China and BRICS bloc
Beijing endorsed Pakistan's mediatory role on 13 May, one day after the BRICS foreign ministers' meeting in New Delhi. Chinese state banks are processing PGSA yuan toll payments; China has not commented on its vessels' continued Hormuz passage, but benefits structurally from a non-dollar toll system it did not design.
Iraq (bilateral passage partner)
Iraq (bilateral passage partner)
Baghdad negotiated a 2-million-barrel VLCC transit without paying PGSA yuan tolls, offering political alignment in lieu of cash. Iraq's position inside Iran's adjacent bloc makes it the natural first bilateral partner and a template for how Tehran structures passage deals with states that cannot afford Western coalition membership.
Bahrain and Qatar (Gulf signatories)
Bahrain and Qatar (Gulf signatories)
Both signed the Western coalition paper while hosting US Fifth Fleet and CENTCOM's Al Udeid base, respectively. Qatar occupies the sharpest contradiction: it is on coalition paper while simultaneously receiving LNG passage through the bilateral Iran-Pakistan track, a position Doha has tacitly accepted from both sides.
