A detained British-Iranian aid worker sentenced to five years in jail in Iran is to face a second trial on new charges, the semi-official Tasnim news agency on Saturday quoted Tehran Revolutionary Court's head Musa Ghazanfarabadi as saying. "Ghazanfarabadi said the charge against (Nazanin) Zaghari (-Ratcliffe) in the new case is security-related but did not say whether it was espionage or another charge," Tasnim reported.
