A 5.9 magnitude earthquake has rocked an area in western Iran near the border with Iraq, in the province of Kermanshah.
The news agency Tasnim reported that about 287 people have been wounded.
About 146 people have been injured, according to the head of the country's agency in charge of handling responses to emergencies and natural disasters, Pirhossein Kolivand, adding that 21 people had been taken to hospital.
Earlier, state media reported that about 120 people had been injured as a result of the earthquake.
"So far we have received reports of 25 injured and fortunately no fatalities," the governor of the western province of Kermanshah, Houshang Bazvand, told the TV station earlier, adding that their injuries were not critical.
State media reported that the two previous earthquakes, with magnitudes of 4.7 and 5.7, had caused damage to buildings in some villages without resulting in casualties.
"Reports indicate that some walls have collapsed, but extensive damage has not been reported," Morteza Salimi, head of the Relief and Rescue Organization of Iran's Red Crescent, told the news agency IRNA.
In May, as many as 133 people were injured when an earthquake struck the southwestern Iranian province of Kohgiluyeh.
Iran is located on a major fault line and suffers from nearly daily earthquakes.
