Hengaw documented the secret execution of Erfan Shakourzadeh, a 29-year-old aerospace researcher, at Qezel Hesar Prison in Karaj on or around 11 May on espionage charges following reported torture.

Key takeaway

A second technically-skilled defendant has been executed inside a fortnight on espionage charges Hengaw documented.

Hengaw, the Norway-based Kurdish human rights organisation that tracks judicial killings inside Iran, documented the secret execution of Erfan Shakourzadeh, a 29-year-old aerospace researcher, at Qezel Hesar Prison in Karaj on or around 11 May 2026 on espionage charges 1. The execution followed reported torture. Family notification preceded any public state announcement; the documentation cycle is the same one Hengaw has used through the conflict to surface judicial killings the Iranian state has not acknowledged in writing.

The case profile mirrors the Najmeh Amini moharebeh-and-Israel charge that Hengaw documented in Mashhad on 9 May . Two defendants in roughly forty-eight hours, both charged on Israel-linked espionage grounds, both technically skilled, both processed outside any public courtroom record. Shakourzadeh's aerospace specialism is what makes his case operationally distinct from earlier humanitarian cases Hengaw has documented. The state's charging template appears to be selecting researchers and technicians whose work intersects with military-relevant capability, rather than dissidents or protest figures, which is a different population from the demographics Hengaw was tracking when it documented the 56-prison hunger strike on 5 May and the Bakrzadeh and Karimpour executions earlier that week.

Hengaw's documentation is the only source for the execution; Iranian state media have not confirmed and no foreign mission has had consular access. The Kurdish-language network behind the monitor has been the most reliable source on Iranian judicial killings through 2026. Qezel Hesar is the same prison where Hengaw has documented multiple secret executions during the present conflict, which is a procedural pattern, not a coincidence. For families of dual-national or expatriate-linked researchers inside Iran, the case is the second data point inside a fortnight that the charging-and-execution loop can run in days rather than months.

For governments preparing diplomatic representations on consular access, the espionage-charge template is the legal mechanism that closes the door. Espionage convictions in Iran's revolutionary courts carry the death sentence and run without public proceedings, which is the procedural feature that lets a 29-year-old aerospace researcher be hanged before the documentation reaches Geneva.

Deep Analysis

In plain English

Erfan Shakourzadeh was a 29-year-old Iranian who worked in aerospace research, the kind of technical field that deals with rockets, drones, and aircraft engineering. He was secretly executed at a prison near Karaj, a city west of Tehran, on charges of spying. The Kurdish human rights group Hengaw, based in Norway, documented the case after monitoring Iranian prison transfers and family notifications. Hengaw recorded the execution as secret because Iran's judiciary published no charge sheet and no execution notice. Iran does not announce these executions. Families often find out only after the fact, and the public inside Iran cannot easily learn about them because the internet has been heavily restricted since the war began in February. Hengaw's job is to make these cases visible to the outside world. Shakourzadeh's case fits a pattern: Iran has been executing technically educated young people on espionage charges throughout the conflict, apparently targeting anyone whose professional knowledge might have been shared with an adversary.

Deep Analysis
Root Causes

Shakourzadeh's prosecution sits at the intersection of two wartime structural pressures on Iran's judiciary.

First, the IRGC's Decentralised Mosaic Defence doctrine, which devolved launch authority to 31 provincial units after the February 2026 decapitation strikes, created an institutional demand for counter-intelligence processing at scale.

Aerospace researchers with knowledge of UAV or missile systems represent a specific category of technical vulnerability under this doctrine: a researcher who could pass specifications, coordinates, or design parameters to an adversary potentially allows targeting of the decentralised units whose survivability depends on positional obscurity.

Second, the wartime internet blackout (operating at 1-4% connectivity since February 2026, ) creates the conditions for secret executions to proceed without the social-media amplification that slowed or complicated some post-2022 cases.

Hengaw's documentation of Shakourzadeh's execution on 11 May is itself evidence of the network's resilience, Kurdish civil society operates through offline contact chains that survive the blackout, but for the broader Iranian public, knowledge of the execution will not travel domestically in real time.

What could happen next?
  • Precedent

    The 'moharebeh and Israel' charge cluster now links professional technical knowledge to a capital offence in wartime, effectively creating a criminal liability for aerospace or defence researchers who had any international academic or professional contact, a chilling effect on Iran's postwar technical reconstruction capacity.

  • Consequence

    Hengaw's wartime documentation methodology, operating through offline Kurdish civil networks under the internet blackout, will form the primary evidential base for any future International Criminal Court or universal-jurisdiction prosecution of Iranian officials for secret executions.

    Long term · 0.71
  • Risk

    The accelerated judicial timeline in Shakourzadeh's case, bypassing the standard 18-36 month appeals cycle documented in 2022-24 cases, suggests Iranian wartime courts are processing a category of aerospace and technical researcher cases under military rather than civilian procedural rules, which may extend to other detained researchers not yet publicly identified.

The Joint War Committee left Hormuz war-risk premiums at $10-14 million per voyage on 25 May, declining to move on Brent's 5% fall. The JWC's protocol requires a UN Security Council resolution or bilateral government certification letter before de-listing, and neither has arrived: a verbal understanding does not satisfy the formal condition the reinsurance market's treaty terms require.
Gulf Arab producers

Saudi Arabia and UAE depend on Hormuz for their own crude exports; Aramco CEO Nasser has warned no oil market recovery arrives until 2027 if the blockade continues past mid-June. Monday's $98.96 Brent settlement shortens nothing for Gulf producers without a signed instrument and a Pentagon mine-clearance timeline that runs up to six months post-ceasefire.
Qatar
Qatar
Qatar holds $12bn of frozen Iranian assets at the centre of the sequencing dispute but cannot release them without explicit US Treasury authorisation, given the original freeze was a US instrument. As the asset-holding state, Qatar's leverage is real but passive: it is the escrow holder, not the decision-maker, and any resolution requires US Treasury sign-off that Trump has withheld.
Pakistan
Pakistan
With both Prime Minister Sharif and army chief Munir simultaneously in Beijing on 25 May, Pakistan has for the first time consolidated its civilian and military mediation tracks under China's roof. Munir's direct Tehran-to-Beijing flight signals that the security and financial threads of the sequencing problem are now being worked in parallel rather than sequentially.
China
China
Beijing hosted Pakistan's principal mediators and Iran's China envoy Ghalibaf simultaneously on 25 May while its banking regulator capped new state-bank lending to five sanctioned refiners. China is simultaneously the most credible third-party underwriter of the $12bn sequencing and the state whose institutions face live OFAC secondary-sanctions exposure if the deadlock persists through GL V's expiry.
United States

Trump posted on 24 May that the blockade holds until a deal is certified and signed, ruling out the informal MOU structure both sides had been building. The 'certified, and signed' condition is the first operational bar Trump has attached in 87 days, but it arrived without an executive instrument, maintaining the gap between posted ultimatum and signed US policy.
