An earthquake was felt in the Iranian capital Tehran on Wednesday, sending hundreds of people running out onto the streets, AFP journalists reported.
The quake measuring 5.2 magnitude struck shortly before 11:30 pm (2000 GMT), according to the seismological center of the University of Tehran.
The epicenter of the tremor was located about 40 kilometers (25 miles) west of the capital.
Authorities have not yet identified any damage or casualties from the quake, the latest in a series to have rattled the Islamic republic.
“We are asking people to stay calm as the traffic itself could create problems,” the Iranian Red Crescent’s Mortza Redmare said on television.
Shortly before midnight, the situation in parts of the capital seemed to have returned to calm.
Iran sits atop several fault lines, and Wednesday’s quake is the latest in a series to have hit the country in little more than a week.
