## Summary

During the night of 6–7 May 2026, several unmanned aerial vehicles entered
Latvian airspace from the direction of Russia. Two drones came down on Latvian
territory; one exploded at a fuel-storage facility in Rēzekne (~40 km from the
Russian border), damaging four empty oil tanks. No casualties. The drones are
assessed as stray Ukrainian long-range drones diverted off course — Ukraine's
foreign minister later linked the diversion to Russian electronic-warfare
jamming. The incident triggered a political crisis: the Defence Minister and,
days later, the Prime Minister resigned.

## Timeline

| Time (7 May) | Event |
|---|---|
| ~03:30 | VUGD receives several 112 calls about a possible fire at the oil-storage facility on Komunāla iela, Rēzekne. |
| 04:09 | Cell-broadcast warning issued to residents of Ludza and Balvi districts, at NBS request. |
| 04:43 | Cell-broadcast warning issued to Rēzekne district — roughly 40 minutes after Ludza/Balvi. Rēzekne city residents report having already heard/seen drones overhead about an hour before receiving the alert. |
| ~05:30 | NBS announces that two UAVs have crashed on Latvian territory; NBS, State Police and VUGD units deploy to the sites. |
| Morning | One crash site confirmed at the Rēzekne oil-storage base. A second crash site is not yet identified (later associated with the Viļāni area, west of Rēzekne). A possible third drone is believed to have exited Latvian airspace. |
| Daytime | Flights restricted up to ~6 km altitude in the eastern border region; commercial aviation unaffected. Schools closed in Rēzekne and Ludza; remote learning in Balvi. French NATO Baltic Air Policing jets scrambled during the alert. |
| ~08:20–08:51 | NBS declares the air-threat alert ended for Balvi, Ludza and Rēzekne districts. |
| 12:00 | Press conference in Rēzekne (AM / NBS / State Police). |
| ~18:00 | Eastern-region flight restrictions lifted. |
| Daytime | Government Crisis Management Council convenes. PM Siliņa states the threat is "a consequence of Russia's war in Ukraine" and asks the Ministry of Defence to clarify why cell-broadcast warnings were issued only after the crash was reported. |

## Aftermath

- **10 May 2026** — Defence Minister Andris Sprūds resigns. He had already
  survived an April Saeima no-confidence-style vote (43 for dismissal, 50
  against).
- **~14 May 2026** — Prime Minister Evika Siliņa resigns; the government falls.
- The Foreign Ministry summoned Russia's chargé d'affaires; Ukraine's foreign
  minister later acknowledged the drones were Ukrainian and attributed the
  diversion to Russian electronic warfare.
- The Ministry of Defence committed to **review and improve the public
  notification / inter-institutional information-exchange algorithms**. The
  Rēzekne incident was designated a central scenario for the "Pilskalns" civil
  protection exercise.

## Prior incidents in the same series (context)

- **7 September 2024** — A Russian "Shahed"-type drone fell in Gaigalava
  parish, Rēzekne district. After-action commitments were made then to speed
  up public notification.
- **25 March 2026** — A stray Ukrainian drone crashed in Krāslava district
  (Dobročina); a parallel drone struck a power-station chimney in Estonia.
- **3 May 2026** — Air-threat cell broadcasts in Alūksne, Balvi, Ludza,
  Rēzekne and Krāslava (~3.5 h); no drone crossed the border.

The 7 May incident is therefore the **fourth comparable event in ~20 months**,
which is why the failure is framed publicly as an algorithm/process failure
rather than a one-off.
