> On 17 June 2026 the United States and Iran signed an interim 14-point memorandum of understanding concerning the cessation of hostilities, providing for an immediate halt to hostilities and a 60-day negotiation period, including arrangements concerning the Strait of Hormuz. Separately, an IOM mobility report dated 22 October 2026 documented a regional escalation that triggered a humanitarian crisis affecting multiple countries and placed pressure on humanitarian access and essential civilian services as of 22 October 2026. According to the same 22 October 2026 IOM report, as likely findings, recurring escalations in Iran disrupted basic services and infrastructure, and maritime and air-transport restrictions affected movement and humanitarian access. IOM/DTM reported, as a likely finding, that population movements in Iran and the wider region remained localized, temporary and economically driven as of 5 October 2026, with no signs of mass displacement. IOM/DTM also likely estimated approximately 217,303 people recorded as displaced in Yemen by 12 October 2026.

- Editorial note: Use this as an OCHA humanitarian report for the March 2026 window; it does not establish the 22 October 2026 conditions or the 17 June memorandum.
- Original: [Open source]()
OCHA frames the escalation as producing humanitarian needs and access pressure across the region.
This source is a humanitarian report from OCHA dated March 2026. Its scope is the humanitarian response to escalation in the Middle East and beyond, and it supports the confirmed finding that regional escalation produced a humanitarian crisis affecting multiple countries and pressure on humanitarian access and essential services.
The report should be read for the March 2026 window only. It is separate from the 17 June 2026 US–Iran cessation-of-hostilities memorandum and from later October 2026 assessments.
#### Takeaways
- Regional escalation had multi-country humanitarian consequences.
- Access and essential services were under pressure in the reported window.
- Use the March 2026 date; do not import later reporting dates.

- Registry title: OCHA Islamic Republic of Iran Humanitarian Update No. 06, 30 June 2026
- Editorial note: Read as an Iran-specific OCHA update for 30 June 2026; it supports the likely Iran disruption picture in claim 4 without establishing the 22 October assessment.
- Original: [Open source]()
The update covers recurring escalation effects on services, infrastructure and humanitarian access in Iran.
This OCHA update is dated as of 30 June 2026 and focuses on the Islamic Republic of Iran. It is one of the sources behind the likely claim that recurring escalations in Iran disrupted basic services and infrastructure and that maritime and air-transport restrictions affected movement and humanitarian access.
The June window is distinct from the later October 2026 reporting windows. Use it only to characterize conditions documented at that date.
#### Takeaways
- Iran faced service and infrastructure disruptions under recurring escalation.
- Maritime and air-transport restrictions affected movement and access in Iran.
- Date is 30 June 2026; do not extend it to October conditions.

- Original: [Open source]()
A UN update on Iran that contributes to the likely picture of disrupted services, infrastructure and movement.
This source is United Nations in Islamic Republic of Iran Humanitarian Update No. 8, dated as of 31 August 2026 and produced with OCHA ROMENA. It supports the likely claim that recurring escalations in Iran disrupted basic services and infrastructure and that transport restrictions affected movement and humanitarian access.
The August reporting window is separate from the 30 June update and from the October 2026 assessments. Do not use it to establish conditions after its stated date.
#### Takeaways
- Iran's disruptions were still documented as of 31 August 2026.
- Transport and access restrictions are part of the likely Iran picture.
- Keep the August date distinct from later windows.
### Yemen displacement recorded at about 217,000 by 12 October 2026

- Publisher: iom.int
- Source type: humanitarian
- Registry title: IOM Yemen Displacement and Movement Update, 12 October 2026
- Editorial note: Read narrowly for Yemen displacement and movement as of 12 October 2026; it supports claims 6 and 7, not all regional displacement or later conditions.
- Original: [Open source]()
IOM data records increased displacement in Yemen after escalation along the West Coast, while broader humanitarian mobility pressures are also documented.
This IOM source is dated 12 October 2026 and addresses Yemen. It supports the likely claim that displacement in Yemen increased after the escalation along the West Coast, with approximately 217,303 people recorded as displaced by 12 October 2026.
The source also contributes to the confirmed finding that the conflict affected humanitarian mobility beyond Iran, including displacement, migration and access challenges in Yemen and other countries in the region. It should not be used to assert figures for the whole region or for returns.
#### Takeaways
- Yemen displacement is approximately 217,303 as of 12 October 2026, likely and approximate.
- Humanitarian mobility pressures extend beyond Iran, including Yemen.
- Do not extrapolate the Yemen figure to all regional displacement.

- Source type: primary\_document
- Registry title: Yemen West Coast Displacement Event-Tracking Dataset (1 August–10 October 2026)
- Editorial note: Read as a primary displacement dataset; its reporting window is 1 August–10 October 2026, not the later 12 October cumulative figure.
- Original: [Open source]()
A primary event-tracking dataset documenting displacement caused by escalation along Yemen's West Coast, with data collected from 1 August to 10 October 2026.
This Displacement Tracking Matrix dataset from IOM Yemen is a primary mobility record. Its documented reporting window is 1 August 2026 through 10 October 2026, and it covers displacement caused by escalation along Yemen's West Coast.
The dossier records that displacement in Yemen increased after the escalation along the West Coast, with approximately 217,303 people recorded as displaced by 12 October 2026, a likely and approximate figure according to IOM/DTM data. This dataset is a DTM Yemen event-tracking source; it should not be read as supplying the final cumulative count itself.
The dataset also falls within the broader documented finding that conflict affected humanitarian mobility beyond Iran, including displacement, migration and access challenges in Yemen.
#### Takeaways
- Primary IOM/DTM event-tracking dataset for Yemen's West Coast displacement.
- Reporting window: 1 August–10 October 2026.
- Consistent with claim 6 as a Yemen displacement record, not the final 12 October figure.
- Scope limited to Yemen; no regional displacement or return figures.

- Registry title: IOM Yemen Humanitarian Update on West Coast Fighting
- Editorial note: Humanitarian update; its 72-hour displacement figure and Eastern Route migrant detail are not independently established in the dossier and should not be repeated as verified facts.
- Original: [Open source]()
A humanitarian update from IOM Yemen on fighting across Yemen's West Coast and its mobility consequences.
This is a humanitarian source from IOM Yemen. It reports on fighting across Yemen's West Coast and the resulting displacement and humanitarian access strain.
The dossier's verified record states that the conflict affected humanitarian mobility beyond Iran, including displacement, migration and access challenges in Yemen and other countries in the region. This update is consistent with that broad claim, but its specific short-window displacement figure is not adopted here.
The excerpt's reference to migrants using the Eastern Route and to them becoming trapped or stranded is not independently supported by the numbered claims. It is treated as source-reported detail only and is not used to extend the verified claims.
#### Takeaways
- Humanitarian reporting by IOM Yemen, scoped to West Coast fighting.
- Consistent with claim 7's general finding on mobility and access challenges in Yemen.
- Do not rely on its 72-hour displacement figure or Eastern Route migrant assertions as verified.

- Registry title: DTM Yemen Emergency Tracking Report, 1 August–29 September 2026
- Editorial note: Interim emergency tracking report; use its recorded cumulative count only as a dated, approximate DTM figure, not as the final 12 October displacement total.
- Original: [Open source]()
An IOM/DTM emergency tracking report covering displacement from 1 August to 29 September 2026, with a cumulative count since escalation began in June 2026.
This primary document is an IOM/DTM emergency tracking report for Yemen. Its documented reporting window is 1 August 2026 through 29 September 2026.
The report records approximately 151,794 individuals displaced between 1 August and 29 September 2026, and a cumulative 152,856 individuals since the escalation began in June 2026. These are dated, approximate DTM figures.
It is consistent with the dossier's likely finding that displacement in Yemen increased after the escalation along the West Coast, but it predates the 12 October 2026 cumulative estimate of approximately 217,303 people and should not be read as that final figure.
#### Takeaways
- Primary DTM emergency tracking report for Yemen.
- Reporting window: 1 August–29 September 2026.
- Records approximately 152,856 cumulative displaced since June 2026.
- Consistent with claim 6 as an interim dated displacement record.

- Publisher: amnesty.org
- Source type: human\_rights
- Registry title: Amnesty Investigation into US-Israeli Strikes on Tehran, March 2026
- Editorial note: Human-rights investigation; its subject predates the 17 June memorandum and is not used as support for the dossier's numbered humanitarian or mobility claims.
- Original: [Open source]()
A human-rights source reporting deadly US-Israeli coalition attacks on densely populated areas of Tehran in March 2026.
This Amnesty International investigation reports US-Israeli coalition attacks on densely populated areas of Tehran in March 2026, stating that the attacks killed and injured dozens of civilians and calling for an independent and impartial investigation.
The dossier does not draw on this source for its claims about the 17 June 2026 United States-Iran memorandum, the 22 October 2026 humanitarian access picture, or the mobility and displacement findings. Its subject is kept separate from those dated records.
The source is therefore characterized narrowly as a human-rights report on a specific set of strikes; it does not independently establish any of claims 1 through 7 in this dossier.
#### Takeaways
- Human-rights source documenting March 2026 strikes on Tehran neighbourhoods.
- Reports dozens of civilian deaths and injuries, and demands independent investigation.
- Not used as support for the dossier's humanitarian or mobility claims.
- Keep separate from the 17 June memorandum and later reporting windows.

- Editorial note: Use only the supplied headline and date; the excerpt does not include the article body, so treat it as a dated news signal rather than a full-source account.
- Original: [Open source]()
The excerpt identifies a Reuters news item dated 6 March 2026, before the 17 June memorandum, on obstruction of global relief efforts.
This is a Reuters news item dated 6 March 2026. The supplied excerpt contains only the headline 'Iran war chokes aid corridors, obstructing global relief efforts' and the publication date, not the article text.
The headline supports the documented pressure on humanitarian access in claim 3, but it does not establish the 22 October 2026 condition or the specific country-level impacts in claims 4–7.
#### Takeaways
- Treat as a dated media report on aid-corridor obstruction.
- Do not infer later humanitarian conditions from this March excerpt.
### A 17 June 2026 Reuters item identifies a 14-point US-Iran pact.
- Registry ID: `src-us-iran-cessation-hostilities-2026-reuters-com-2`
- Publisher: reuters.com
- Source type: news
- Registry title: Reuters report on the 14-point US-Iran pact sent to Congress
- Editorial note: The excerpt establishes only that Reuters published a 14-point pact item on 17 June 2026; it does not by itself show the 60-day period or Hormuz arrangements.
- Original: [Open source]()
Reuters reported on 17 June 2026, updated 18 June, that the White House sent a 14-point US-Iran pact to Congress.
The source is a Reuters news item dated 17 June 2026 and updated 18 June 2026. The supplied excerpt includes the title 'The 14-point US-Iran pact White House sent to Congress' and a photograph caption, but no article body.
This supports claim 2's characterization of the agreement as a 14-point interim pact. The excerpt does not independently document the immediate halt, the 60-day negotiation period, or the Strait of Hormuz arrangements; those elements rest on claim 2 and its listed evidence.
#### Takeaways
- Use this source for the 14-point label and the 17 June reporting date.
- Keep the 60-day and Hormuz terms attributed to claim 2, not to this excerpt.

- Registry title: Chatham House expert comment on whether the US-Iran ceasefire will hold
- Editorial note: This is a think-tank commentary, not a primary record of the memorandum; use it only for the post-agreement debate it frames.
- Original: [Open source]()
Chatham House published an expert comment on 22 June 2026 assessing the durability of the US-Iran ceasefire.
The source is a Chatham House expert comment published 22 June 2026. Its supplied excerpt gives the title 'Will the US–Iran ceasefire hold?' and states that both sides want to buy time, while midterm elections, Israel, and deep mistrust may intervene.
It supports claim 1's documented cessation of hostilities only as a secondary reference to the existence of a ceasefire; it does not establish the 14-point terms in claim 2 or the humanitarian conditions in claims 3–7.
#### Takeaways
- Use as commentary, not as evidence for agreement terms.
- Do not treat midterm, Israel, or mistrust factors as verified claims.
### A September 2021 SIPRI report addresses EU sanctions and humanitarian impact regarding Iran.

- Publisher: sipri.org
- Source type: research
- Registry title: SIPRI report on EU and sanctions regimes against Iran
- Editorial note: This is a pre-2026 sanctions report; it does not directly support the 2026 escalation claims and should be read as background on the sanctions environment.
- Original: [Open source]()

The source is a SIPRI research report dated September 2021 by Kolja Brockmann and Keith A. Preble. The supplied excerpt includes the title, authors, and contents covering US, UN Security Council, and EU sanctions on Iran.
It does not directly establish any of the 2026 numbered claims in this batch. Its relevance is limited to background on the pre-existing sanctions environment, not to the documented humanitarian access conditions as of 22 October 2026.
#### Takeaways

## Open questions
- Whether the 60-day negotiation period produced any durable follow-on arrangement after it ended.
- Reconciliation of the 22 October 2026 IOM report's Iran access and service findings (likely) with other humanitarian reporting; do not use the 5 October DTM mobility assessment as evidence of later conditions.
- Reconciliation of the Yemen displacement count (approximately 217,303 by 12 October 2026, per IOM/DTM, likely) with later IOM/UNOCHA totals; do not merge with Iran movement descriptions.
- Status of maritime and air-transport restrictions on humanitarian access in Iran after 22 October 2026.
- Whether localized economically driven movements become longer-term if essential services remain disrupted.
