A transportation minister has resigned and a station manager has been arrested in Greece following a head-on crash between a passenger and freight train that has left at least 57 dead, with officials fearing the death toll will rise.
The developments surrounding the collision in Tempe come as Greek Prime Minister Kyriakos Mitsotakis said during a televised speech that "Everything in this tragedy points, unfortunately, mainly to human error."
As of Thursday, 57 people have been confirmed dead in the disaster and around 50 remain hospitalized in northern Greece. More than 300 people were onboard the train late Tuesday when the accident happened.
"We can see that there are more [bodies of] people there," Fire Service spokesman Yiannis Artopios reportedly told state television. "Unfortunately, they are in a very bad condition because of the collision."

The Larissa station manager arrested after the collision was charged Wednesday with multiple counts of manslaughter and causing serious physical harm through negligence, as a judicial inquiry tries to establish why the two trains were traveling in opposite directions on the same track.
But the 59-year-old worker in charge of signalling has denied any wrongdoing and is blaming the crash on a possible technical failure, according to the BBC.

Railway workers’ associations, meanwhile, called strikes Thursday, halting national rail services and the subway in Athens.
They are protesting working conditions and what they described as a dangerous failure to modernize the Greek rail system due to a lack of public investment during the deep financial crisis that spanned most of the previous decade and brought Greece to the brink of bankruptcy.
