ISTANBUL (AP) — Doctors, nurses and an ambulance driver are among 47 people on trial accused of causing the deaths of 10 infants as part of an alleged scheme to defraud Turkey’s social security system. The defendants are accused of transferring babies to neonatal units of 19 private hospitals where the infants were allegedly kept for prolonged and sometimes unnecessary treatments. At least 10 newborns are alleged to have died in the past year due to neglect or malpractice in facilities that were unprepared to treat them.

Prosecutors at the trial, which opened in Istanbul on Monday, say the defendants also falsified reports to make the babies’ condition appear more serious with the aim obtaining payments from the social security institution. The main defendants have denied any wrongdoing, insisting they made the best possible decisions and face punishment for unavoidable unwanted outcomes. The case, which emerged last month, has sparked public outrage and calls for a greater oversight of the health care system.

Authorities have since revoked the licenses and closed nine of the 19 hospitals that were implicated in the scandal. Dr. Firat Sari, the main defendant who operated the neonatal intensive care units of several private hospitals in Istanbul, is facing a sentence of up to 583 years in prison.

He is charged with establishing an organization with the aim of committing a crime, defrauding public institutions, forgery of official documents, and homicide by negligence. D.
