A massive power outage has caused chaos across Turkey, shutting down metro networks in Istanbul and the capital Ankara and affecting flights.
It's been called the worst power cut in 15 years, hitting almost all of the country's provinces, from the Greek border to the south- east.
People have become trapped in elevators and rescue crews rushed to subway stations to evacuate stranded travellers.
A crisis centre has been set up at the energy ministry, which is investigating the possibility of a cyber attack.
