Iran Conflict 2026- What is Karaj?
- Karaj is Iran's fourth-largest city, located 40 km west of Tehran in Alborz Province, with a population of around 1.97 million. It is both an industrial hub and the site of Iran's TESA/TABA Centrifuge Manufacturing Complex, destroyed by Israeli strikes in June 2025.Source: Lowdown
- Was the Karaj centrifuge facility destroyed?
- Yes. Israeli strikes in June 2025 demolished both main manufacturing buildings of the TESA/TABA complex. Satellite imagery confirmed total destruction with no cleanup or reconstruction visible as of March 2026.Source: Lowdown / satellite imagery
- Has Karaj been bombed in the 2026 Iran-Israel war?
- Yes. On 23 March 2026, Israel struck Karaj alongside Tehran, Isfahan, and Ahvaz in what Al Jazeera's correspondent called 'unprecedented in size and volume.' Earlier strikes targeted the Tehran-Karaj fuel depot corridor, causing toxic black rain and civilian supply shortages.Source: Al Jazeera
- How far is Karaj from Tehran?
- Karaj is approximately 40 km west of Tehran, connected by motorway and metro. The two cities share infrastructure and supply chains, meaning wartime disruptions in Tehran directly affect Karaj residents.Source: Lowdown
- What is the difference between Karaj and Tehran in the Iran war?
- Karaj is a separate city but functions as a western extension of Tehran. It housed Iran's centrifuge manufacturing complex, making it a higher-value nuclear target than most of Tehran's residential districts, while sharing the capital's civilian supply crises.Source: Lowdown
- What is Karaj and why does it matter in the Iran war?
- Karaj is Iran's fourth-largest city, 40 km west of Tehran, hosting the destroyed TESA/TABA centrifuge manufacturing complex and Qezel Hesar Prison, the primary site for wartime executions of protest-era detainees.Source: Lowdown
- Where is Qezel Hesar Prison?
- Qezel Hesar Prison is in Karaj, Alborz Province, approximately 20 km west of central Tehran. It has become the primary documented site for wartime executions of protest-era detainees during the 2026 Iran conflict.Source: Hengaw
- Has Karaj been bombed in the Iran-Israel war?

Background
Karaj, capital of Alborz Province, sits 40 km west of Tehran on the edge of the Alborz mountain range. With a population of roughly 1.97 million, it is Iran's fourth-largest city and functions as an industrial and residential extension of the capital, linked by motorway and metro.
The city's nuclear significance rested on the TESA/TABA Karaj Centrifuge Manufacturing Complex, which produced components for Iran's uranium enrichment programme and operated under IAEA monitoring within the JCPOA framework. Israeli strikes in June 2025 demolished both main manufacturing buildings; satellite imagery confirmed the site remains destroyed with no visible reconstruction. In March 2026, Karaj was struck again alongside Tehran in what Al Jazeera's correspondent described as "unprecedented in size and volume."
Karaj is also home to Qezel Hesar Prison (also known as Ghezel Hesar), which has become the primary documented site for wartime executions of protest-era detainees during the 2026 conflict. On 27 April, Jafar Fakhrabadi was executed at Yazd Central Prison, with three Ali Fahim co-defendants transferred to solitary at Qezel Hesar in an imminent-execution signal.
The city's proximity to Tehran means Karaj shares the capital's wartime crises: toxic black rain from Israeli-struck fuel depots fell across the Tehran-Karaj corridor, with the Iranian Red Crescent warning of chemical burns and lung damage.
