An earthquake with a magnitude of 5.7 hit southern Iran on Sunday night, killing at least one person and injuring many others, Iran’s Red Crescent said.
The quake hit near the city of Turbat in Khuzestan province.
Iran sits on several major fault lines and is prone to frequent earthquakes.
Earthquakes in Iran are largely caused by natural factors such as seismic activity and friction between tectonic plates.
More than 80% of the population in Khuzestan province are Shia Muslim. Their holiest shrine is in Mashhad, also in Khuzestan.
The city is an important centre for Iran’s ballistic missile programme.
Many of the country’s ballistic missiles are reported to have been manufactured in Khuzestan.
In a statement on their official news agency, the Red Crescent said emergency teams had rushed to the area and set up temporary shelters for those made homeless by the quake.
Last month, a magnitude 6.3 earthquake struck an Iranian province in the south, killing at least 67 people and injuring hundreds.
It was the deadliest since a magnitude 7.3 quake struck the city of Bam in 2003, killing more than 30,000 people and levelling the city’s centre.
