The death toll from Tuesday’s train crash in Greece has increased to 57.

Eleni Zaggelidou, one of ten coroners working on the investigation, said DNA had been taken from 57 intact bodies.

Rail workers held a one-day strike on Thursday following the disaster, blaming government neglect. While Zoe Rapti, Greece’s deputy minister of health, said austerity during Greece’s economic crisis in the 2000s had contributed to a lack of investment in the railways, she however promised that a “wide investigation” would take place, which would provide answers.
