WHO Classification

The World Health Organization has formally declared the Ebola outbreak spanning the DRC and Uganda a Public Health Emergency of International Concern, the highest alert level under international public health law. Cross-border transmission risk in the Great Lakes corridor remains uncontained.

SRM Alert

All personnel and implementing partners active in eastern DRC and Uganda must immediately review health protocols, medical evacuation plans, and PPE requirements. A dedicated SRM Great Lakes Health Security Advisory is forthcoming.

02Indictment of Raúl Castro

Diplomatic escalation · Americas security environment

24 February 1996
Cuban military aircraft shot down two civilian planes by Brothers to the Rescue. Four U.S. citizens killed. Cuba denies criminal liability.
1996 – 2024
Incident remains a persistent flashpoint across multiple U.S. administrations. No individual accountability established. Cuba declines extradition.
21 May 2026 — Today
U.S. federal grand jury formally indicts former Cuban President Raúl Castro. Most significant legal escalation in decades. Bilateral frameworks near total collapse.
Operational Implication

Organizations operating under U.S. federal funding or reliant on U.S.–Cuba travel and trade frameworks should anticipate accelerating restrictions. Diplomatic channels likely suspended near-term. Monitor State Department advisories closely.

U.S.–Iran · Nuclear Track

Negotiations Enter "Final Stages"

Trump describes talks as nearing conclusion; significant gaps remain. Tehran weighs the latest U.S. proposal. The outcome defines the security architecture of the Gulf and cascades into proxy dynamics across the Middle East and Horn of Africa.

Israel–Gaza · Humanitarian Track

Ben-Gvir Faces Global Condemnation

Far-right National Security Minister Ben-Gvir attracted international condemnation after footage showed him taunting detained Gaza flotilla activists. The incident amplifies diplomatic pressure and may trigger new access restrictions for humanitarian actors.

SRM Watch

Breakdown scenario: rapid military posture escalation. Monitor within 72-hour windows as talks progress.

SRM Watch

Organizations active in Gaza or engaged in flotilla-related advocacy should immediately assess reputational and operational exposure.
