The latest earthquake hit in the west of the Middle Eastern country in the same area that was starting to recover after more than 600 people were killed in the region in November.
A number of aftershocks affected the area after the initial earthquake.
The earthquake hit Iran’s western province of Kermanshah.
The semiofficial ISNA news agency says the Kurdish town of Sarpol-e Zahab, about 520 kilometers west of Tehran, was near the epicentre of the quake.
The earthquake struck near where a 7.3-magnitude earthquake hit in November, killing more than 600 people and injuring more than 9,000.
Some 50 percent of the casualties occurred in Sarpol-e Zahab during that earthquake.
Iran has several major seismic faults within its territory and often experiences quakes.
