Iran said on Sunday that no fatalities had been reported but that more than 400 people were injured after an earthquake of magnitude 6.3 struck near its western border with Iraq, Iranian state TV reported.
The tremor was also felt in the Iraqi capital Baghdad and in Kuwait.
"We have had 411 injured, 80 percent of whom have been treated and released ... No fatalities have been reported," Houshang Bazvand, governor of the western province of Kermanshah, told state TV.
Fears of aftershocks sent people in several cities in Kermanshah province out onto the streets and parks in cold weather, Iranian media reported. Rescue teams were immediately deployed to the quake-hit area.
"No reports of any fatalities yet and most of the injured were hurt while fleeing, not due to quake damage," Pirhossein Koulivand, head of Iran's emergency services, told state TV.
State TV reported minor damage at some buildings in the area. The quake triggered landslides but officials said all the roads in the area remained open to traffic and that electricity had been restored in most of areas hit by the tremor.
