An explosion occurred outside the offices of Hellenic Train in Athens, Greek police said on Friday, adding there were no immediate reports of injuries.
Police cordoned off the area after two Greek media organizations received warning calls that an explosive device would go off within 35 minutes, police officials said.
A suspicious-looking bag was spotted outside the building which was evacuated.
An investigation is under way. A police official said the cause was likely a makeshift bomb.

There was no immediate claim of responsibility.
Hellenic Train is a unit of Italy's Ferrovie dello Stato, which operates passenger and freight routes in Greece.
A deadly 2023 train crash, Greece's worst rail disaster, killed 57 people, mostly students, and injured dozens.
Many Greeks view the crash as emblematic of the neglect of the country's railways in recent decades and also of a persistent failure by the state to address safety concerns.

Two years after the crash, the safety gaps that caused the crash have not been filled, an inquiry found earlier this year.
A separate judicial investigation remains unfinished and no one has been convicted in the accident, leading to outrage among Greek citizens.
Prime Minister Kyriakos Mitsotakis' right wing government, which won re-election after the crash in 2023, has faced repeated criticism by relatives of the victims for failing to initiate a parliamentary inquiry into political responsibility.
Mitsotakis' government denies wrongdoing and says it is up to the judiciary to investigate the accident, leading to allegations of corruption.

In a survey carried out this week by Pulse pollsters, 82 per cent of Greeks asked said the train disaster was "one of the most" or "the most" important issue in the country and 66 per cent said they were dissatisfied with the investigations into the accident.
