An earthquake hit Iran early Thursday just 60 miles away from the country's only operating nuclear power plant. According to the USGS, the 5.5 magnitude quake struck 6.2 miles below the surface, strong and shallow enough to cause widespread damage, though Iran hasn't reported damage at the Bushehr nuclear plant, which was built to withstand earthquakes. Iranian state media put the earthquake's strength at magnitude 5.9, though there were no immediate reports of casualties, the National reports. The earthquake was felt as far away as Bahrain, Kuwait, and Qatar, where tall buildings were evacuated, the AP reports. (More Iran earthquake stories.)
