Massive power outages hit Spain, Portugal and parts of France, causing flight cancellations and affecting transport, telephone lines and traffic lights in major cities. Spanish Prime Minister Pedro Sanchez announced a state of emergency in the regions of Madrid, Andalusia and Extremadura.

Many areas in Spain have endured nearly nine hours without power, with metros and trains stopping service and major cities experiencing traffic gridlock. It was the second serious European power outage in less than six weeks after a March 20 fire shut down Heathrow Airport in the UK.
