TEHRAN, Iran -- A magnitude-6.1 earthquake killed at least 37 and injured hundreds more Tuesday in a sparsely populated area in southern Iran, officials said, adding that it did not damage a nuclear plant in the region.

The report said the earthquake struck the town of Kaki, 60 miles southeast of Bushehr, a town on the Persian Gulf that is the home of Iran's first nuclear power plant, built with Russian help.

"No damage was done to Bushehr power plant," Bushehr provincial governor Fereidoun Hasanvand told state TV. He said 37 people had died so far and 850 were injured, including 100 who were hospitalized.

The plant's chief, Mahmoud Jafari, confirmed the site's condition to the semiofficial Mehr news agency, saying it is resistant to earthquakes of up to magnitude eight.

Water and electricity were cut to many residents, said Ebrahim Darvishi, governor of the worst-hit district, Shonbeh.

The International Atomic Energy Agency, the United Nations' nuclear watchdog agency, said on its website it had been informed by Iran there was no damage to the plant and no radioactive release and, based on analysis of the quake, was not seeking additional information. The IAEA statement indicated that it was satisfied there was little danger.

Shahpour Rostami, the deputy governor of Bushehr province, told state TV that rescue teams have been deployed to Shonbeh.

Three helicopters were sent to survey the damaged area before sunset, said Mohammad Mozaffar, the head of Iran's Red Crescent rescue department. He said damage was particularly bad in the village of Baghan.

Kaki resident Mondani Hosseini told The Associated Press that people had run out into the streets out of fear.

Dozens of aftershocks were reported by the official IRNA news agency.

Iran announced three days of mourning.

The quake was felt across the Gulf in Bahrain, the United Arab Emirates and Qatar, where workers were evacuated from high-rise buildings as a precaution.

On Sunday, a lighter earthquake jolted the nearby area. Iran is located on seismic faults and earthquakes are frequent.
