A power cut affected several areas of Athens on Wednesday, disrupting parts of the capital's subway system, witnesses said.
A passenger at Athens's Sytagma rail station said there was an announcement over the public address system that power was down and customers were advised to leave.
A source in the city's subway network said people were asked to leave after the blackout affected about a quarter of the outbound traffic from Sytagma, the main metro station in the centre of the capital.
Another source said there was a fault at a sub station close to the capital which had a capacity of 150 kilovolts.
Elsewhere, people reported that traffic lights were not working in some areas of the city.
