Iranian authorities have executed at least six people accused of spying for Israel since the conflict between the Islamic Republic and the Jewish state broke out two weeks ago.

Iran hanged three men on Wednesday — identified as Idris Ali, Rasoul Ahmad Rasoul, and Azad Shojai — over espionage charges, according to reports. Iran previously executed three other men following Israel’s airstrike operation on June 13: Mohammad Amin Mahdavi Shayesteh, Majid Masibi, and Esmail Fekri.
