TEHRAN, Iran (AP) — An earthquake of at least magnitude 5.5 struck in southern Iran near the country's sole nuclear power plant on Thursday morning, shaking countries across the Persian Gulf. There was no immediate report of damage or injuries. 
 
 The U.S. Geological Survey said the quake struck at 0634 GMT some 100 kilometers (60 miles) east of Bushehr. That's home to the Bushehr Nuclear Power, the only operating nuclear power plant in the Islamic Republic. 
 
 The USGS put the earthquake's magnitude at 5.5 while Iranian state television, citing officials, described the quake as a magnitude 5.9. Varying magnitudes are common immediately after a temblor. 
 
 Iranian state TV did not report any damage at Bushehr plant, which has seen other earthquakes in the past and is built to resist damage from a temblor. It put the earthquake's epicenter near the town of Kaki. 
 
 The Iran Red Cross described the epicenter as being in a sparsely populated area. 
 
 In Bahrain, an island kingdom off Saudi Arabia, people said they felt the quake and evacuated from high-rise buildings. Some in Qatar also felt the quake and evacuated tall buildings in Doha's West Bay area. People in Kuwait City also felt the temblor. 
 
 The USGS put the earthquake's depth at 10 kilometers (6.2 miles) below the surface. Shallow earthquakes often have broader damage. 
 
 A magnitude 5 earthquake can cause considerable damage. 
 
 Iran sits on major fault lines and is prone to near-daily earthquakes. In 2003, a 6.6-magnitude quake flattened the historic city of Bam, killing 26,000 people. Bam is near the Bushehr nuclear plant, which wasn't damaged at that time. 
 
 In November, a major 7.3 magnitude earthquake struck a mountainous region of Iran near the Iraqi border, killing over 530 people and injuring thousands in Iran alone. In Iraq, nine people were killed and 550 were injured, all in the country's northern Kurdish region.

 A magnitude 5.9 earthquake on Thursday struck Iran's southern province of Bushehr, which is home to a nuclear power plant, state television reported. 
 
 There were no immediate reports of casualties or damage. 
 
 The semi-official Tasnim news agency, citing officials, described the quake as a magnitude 5.9. Varying magnitudes are common immediately after a temblor. 
 
 "The quake hit the Kaki area in the province this morning," the news agency said. 
 
 Many houses in rural parts of the province are made of mud bricks, which have been known to crumble easily in quake-prone Iran. 
 
 Iran sits on major fault lines and is vulnerable to near-daily earthquakes. 
 
 In 2003, a 6.6-magnitude quake flattened the historic city of Bam, killing 26,000 people. 
 
 In Bahrain, an island kingdom off Saudi Arabia, people on social media said they felt the quake and evacuated from high-rise buildings. 
 
 The Bahrain Seismic station of the Meteorological Directorate had detected at 9:34 am Bahrain local time an earthquake, 243 km to the North East of Bahrain, with a magnitude of 5.7 Richter scale and with 41.8 km depth.

– 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.
