A gas explosion ripped through the 14th floor of Pamchal Tower 9 in Tehran’s Chitgar district on Thursday, injuring at least four people, according to Iranian state broadcaster IRIB. The high-rise, also known as the Armed Forces Judicial Staff Tower, stands on Hamedani Highway near Chitgar Lake in western Tehran. Emergency crews evacuated residents and contained the resulting fire while investigators cordoned off the site. Details of the blast remain under investigation, but fire and emergency officials told local media a gas leak was the most likely cause. Some independent outlets citing rescue personnel said up to seven people were hurt. Authorities have not reported fatalities or structural collapse, and no information has been released on possible damage to adjoining apartments or offices. Thursday’s incident is the second high-profile residential-tower explosion in Tehran in recent weeks. On 26 June, an apartment at the luxury Aseman (Sky) Tower in the Farmaniyeh neighborhood caught fire after a reported explosion; no official casualty figures were issued and the cause has yet to be disclosed. The back-to-back events have renewed scrutiny of gas-safety standards and emergency-response protocols in the Iranian capital’s high-rises.
