Italy begins the trial of 4 Egyptian officers in absentia on charges of Regeni's murder. At the top of the lists of witnesses in the case appear the names of Egyptian President Abdel Fattah El-Sisi, former Italian Prime Minister Matteo Renzi, and former Foreign Minister Paolo Gentiloni.
Giulio Regeni, a graduate student at the British University of Cambridge, disappeared in Cairo in January 2016. His body was found a week later, dumped in one of the entrances to Cairo.
