Greek Infrastructure and Transport Minister Kostas Karamanlis has stepped down over the deadly train collision in the country.
A passenger train and a freight train crashed head-on in the central town of Tempe late on Tuesday. Police and fire authorities said on Wednesday that 38 people have so far been confirmed dead in the accident. Some cars burst into flames after the collision. The officials said they are continuing the search for the missing.
Karamanlis announced his resignation on Wednesday. He said he was taking responsibility for the long-lasting errors of the Greek political system.
"Everything shows that the drama was, sadly, mainly due to a tragic human error," Mitsotakis said in a televised address.
The country's media reported that police arrested the stationmaster of the station managing operations in an area including the accident site. The reports said he is accused of negligence resulting in death and other charges.
The local media also said traffic lights and the system to oversee train operations had not functioned.
