New trial in Rome of four Egyptians accused over Giulio Regeni killing

Defendants are being tried in absentia over kidnapping and murder of Italian student in 2016

Four Egyptian security officials have gone back on trial in absentia in Rome on charges related to the kidnap and murder of an Italian student in Cairo.

Giulio Regeni, 28, had been conducting research when he was abducted in January 2016. His body was found nine days later, dumped on the outskirts of the Egyptian capital, bearing extensive signs of torture.
