There were 60 million affected persons, thousands of people trapped in trains, and ten deaths.

Omissions

• The claim attributes all 60 million affected and all deaths solely to Spain, but the blackout affected the entire Iberian Peninsula including Portugal, Andorra and parts of France. The combined population of Spain (~48 million) and Portugal (~10 million) is approximately 58 million, making '60 million affected' accurate for the region but not for Spain alone. The 'ten deaths' figure is slightly higher than initial confirmed reports of 8 deaths (7 in Spain, 1 in Portugal), though later epidemiological studies suggested higher excess mortality.
• The claim was made on April 29, 2026, one year after the event, when more comprehensive mortality studies showing approximately 147 excess deaths were already available.
• Two independent sources or one primary source confirming the exact figures could not be found; the verdict relies on secondary journalistic sources and Wikipedia.
