Iran’s notorious Evin prison is operating once again.

Two months after Israel attacked and severely damaged the compound, where political dissidents were detained, the authorities have returned about 600 inmates to two refurbished wards that sit amid the larger ruins of the prison.

The prisoners, whose return the judiciary announced this month, are all male and include many prominent political figures and dissidents. Photographs in Iranian news media show the two wards repaired — broken windows and blown-out doors were reinstalled, and damaged rooms and hallways were cleaned of debris.

But the rest of the prison compound remains largely destroyed. Israel’s strikes on June 23, part of a 12-day war with Iran, collapsed the prison’s administrative buildings, visitor and recreational centers, hospital and other housing facilities, all of which have not been reconstructed, according to testimonies from prisoners and interviews with families, lawyers and activists in Iran.

Israel’s targeting of Evin prison was the deadliest single attack of the war, killing 80 people and injuring dozens of others, according to Iran’s Ministry of Health. In addition to prisoners, those killed included prison staff, social workers, a child, relatives of prisoners, medical staff, the prison's chief prosecutor and at least one passer-by.

The damage to Evin was so extensive that many in and outside the country speculated that the prison would not reopen for months, if ever.
