TEHRAN, Nov 26 (Reuters) - An earthquake of 5.6 magnitude jolted a mountainous area of southern Iran on Friday but Iranian media said that so far there were no reports of casualties.
"The quake took place at 1603 local time (1233 GMT) near Firouzabad in the Fars province. It jolted the mountainous area," Iran's state TV quoted Tehran University's Seismological Centre as saying.
"So far there has been no reports of possible casualties," the official IRNA news agency said.
The U.S. Geological Survey put the quake's magnitude at 5.6 and said it was 10.1 km (6.3 miles) deep.
Iran, the world's fourth-largest oil producer, is criss-crossed by major faultlines and is frequently hit by earthquakes. In 2008 a magnitude 6.1 quake struck Bandar Abbas, on the mainland near the southern Qeshm island, killing at least seven people and injuring 40.
An earthquake in 2003 flattened the desert citadel city of Bam and killed 31,000 people. (Reporting by Parisa Hafezi, writing by David Stamp)
