Israel's attack on the Evin Prison in Iran's capital, Tehran, on June 23 killed 71 people, Iranian judiciary spokesperson Asghar Jahangir claimed on Sunday.

At the end of an air war with Iran, Israel struck Tehran's most notorious jail for political prisoners, in a demonstration that it was expanding its targets beyond military and nuclear sites to aim at symbols of Iran's ruling system.

“In the attack on Evin prison, 71 people were martyred, including administrative staff, youth doing their military service, detainees, family members of detainees who were visiting them, and neighbours who lived in the prison’s vicinity,” Jahangir said in remarks carried on the judiciary's news outlet, Mizan.

Jahangir had previously said that part of Evin prison's administrative building had been damaged in the attack, and people were killed and injured. The judiciary added that the remaining detainees had been transferred to other prisons in Tehran province.

Evin prison holds a number of foreign nationals, including two French citizens detained for three years.

France claims Israeli strike to free prisoners was "unacceptable"

"The strike targeting Evin prison in Tehran put our citizens, Cecile Kohler and Jacques Paris, in danger. It is unacceptable," France's Foreign Minister Jean-Noel Barrot had said on X/Twitter after the attack.

France in May filed a case at the World Court against Iran for violating the right to consular protection, a bid to pressure Iran over the detention of its two citizens.

Barrot, who asked that French diplomatic staff be given access to them as quickly as possible, said they had not been impacted by the damage on site.
