A massive power outage hit Prague and parts of Czechia on Friday, cutting electricity to over 100,000 homes and disrupting metro and tram services.
ATMs stopped working and emergency crews rescued people trapped in elevators.
The blackout began in the afternoon and was traced to a substation malfunction in Chodov.
Metro lines A and C resumed service quickly, while trams and other systems took longer to recover.
Authorities confirmed there is no sign of a cyber or terror attack.
Power has now been restored in most areas as officials continue investigating the cause.
