A significant power outage has struck large parts of Spain, Portugal, and southwestern France, resulting in chaos and disruption across the region. Millions of people are left without electricity as blackout conditions impact transportation networks, traffic lights, and mobile communications. Authorities link the blackout to a rare atmospheric phenomenon, raising concerns about the duration of the outage, which could last up to 10 more hours. In Madrid, the ongoing Madrid Open has been interrupted due to the power cut, while other cities also face significant operational challenges, including suspended train services and halted flights. Officials have confirmed that there is no evidence of a cyber-attack, although the exact timeline for restoring power remains uncertain.
