At least 71 people were killed in an Israeli airstrike on Tehran's Evin Prison during the recent 12-day conflict between Iran and Israel, the Iranian judiciary confirmed on Sunday.

The announcement comes just days after a ceasefire brought a temporary halt to the intense cross-border hostilities.

The strike, which occurred on Monday, reportedly hit the administrative wing of Evin Prison a high-security facility in northern Tehran known for housing political detainees and foreign nationals.

Human rights groups have long flagged the prison for its treatment of inmates, including prominent activists and international citizens.

Judiciary spokesperson Asghar Jahangir stated that the fatalities included prison staff, security personnel, inmates, visiting family members, and nearby residents.

“The latest figures show that 71 people lost their lives in the Evin prison attack,” Jahangir said, adding that the bombardment was part of Israel’s wider offensive launched on June 13.

Photos released by the judiciary revealed the extent of the destruction shattered walls, crumbling ceilings, and debris scattered across waiting rooms and administrative corridors.

Officials also confirmed that the prison’s medical unit and visitor reception areas were among the sections struck.

In the aftermath of the bombing, Iranian authorities began relocating prisoners to undisclosed locations. The judiciary confirmed the transfers but withheld specific numbers and identities of those moved.

Evin Prison has held a number of high-profile inmates over the years, including Nobel Peace Prize laureate Narges Mohammadi and several European nationals, among them French citizens.

The strike has further strained tensions between Tehran and Tel Aviv, amid growing international concern over civilian casualties and the targeting of sensitive sites.
