An explosion in a battery workshop southwest of Tehran on Friday killed one person, injured 10 others and damaged dozens of buildings and cars, state news agency IRNA reported. The blast occurred at 5:15 pm (1245 GMT) on the ground floor of a three-storey residential building, local fire brigade chief Iraj Torkamani told IRNA. The fire from the explosion "was so severe that a worker immediately died and 10 of the residents from 25 apartments in the building were lightly injured," he said. More than 20 cars and some buildings in the vicinity of the blast were also damaged, he added. Torkamani told Tasnim news agency that the cause of the explosion was still unclear and investigations were underway. The incident is the latest in a series of fires and explosions that have hit military and civilian sites across Iran since June. amh/sw
