From The New York Times:
An earthquake on Tuesday shook Tehran, a city on edge after months of war, with residents across the metropolis saying the ground jolted and rolled around midnight.
Tehran, the sprawling capital of Iran with almost 10 million residents, sits on or near several major fault lines and is occasionally hit by earthquakes. Though the earthquake was moderate in magnitude and no casualties or major damage have been reported, it still shocked many of the city’s residents. “We shook as if we were in a swing,” said Saboor, a Tehran resident, who asked that only his last name be used out of fear of retribution.
