A magnitude 5.3 earthquake has hit western Iran, injuring at least 54 people, hours before a more moderate tremor shook an area near the capital Tehran, state media report.
There were no immediate reports of casualties or damage after the later, magnitude 4.2, earthquake which shook an area about 90km from Tehran, the official news agency IRNA reported on Sunday.
Most of the 54 injured were released after receiving treatment in hospitals in the western province of Kermanshah, IRNA quoted Iran's medical emergency services as announcing.
Iranian news agencies said most of the injuries were minor, with some people being hurt by falling items.
A magnitude 7.3 earthquake that shook Kermanshah and neighbouring Iraq in November killed more than 600 people and injured more than 8000.
