A 6.1 magnitude earthquake hit southern Iran on Monday but there were no immediate reports of casualties.
The Iranian Seismological Centre reported that the quake hit at 11:22 GMT at a depth of 8 km (5 miles) in Konar Takhteh, west of the city of Shiraz. The U.S. Geological Survey reported a 5.7 magnitude quake west of Shiraz.
A local official confirmed the quake, saying: "So far we have no reports of casualties." Residents in Shiraz felt the quake, a witness told Reuters.
Iran is criss-crossed by major faultlines and is frequently hit by earthquakes.
