Timeline for Karaj

Background

Karaj is a city in Alborz Province, west of Tehran, and an industrial and residential extension of the capital. Its position on the Tehran corridor gives it importance beyond its local population, linking it to the capital’s transport, manufacturing and security geography.

The city contains the TESA/TABA centrifuge manufacturing complex, a site associated with components for Iran’s uranium-enrichment programme. Karaj was among the cities hit during large-scale Israeli strikes on 22 March 2026, alongside Tehran, Isfahan, Ahvaz and Bandar Abbas.

Karaj also contains Qezel Hesar Prison, whose name recurs in reporting on executions of protest-era detainees during the 2026 war. The prison’s role makes Karaj relevant to both the nuclear infrastructure story and the domestic repression documented during the conflict.

Key Issues
Political executions

Karaj anchors wartime executions

On 20 April, Ali Fahim was executed at Qezel Hesar Prison in Karaj, the fourth execution linked to one protest case from the same Karaj Revolutionary Court branch. The prison therefore became a named site in reporting on the state’s handling of people detained during the January protests.

The pattern continued on 1 June, when Ashkan Maleki and Mehrdad Mohammadinia were hanged at Ghezel Hesar after arrests during those protests. According to Hengaw, authorities denied their families final visits and withheld their bodies. For Karaj, the prison gives the city a continuing place in the conflict’s domestic human-rights record, rather than merely its geographic proximity to Tehran.
