Hossein Rahnimi, the head of a local hospital, said many of the injured also suffered panic attacks. The earthquake struck western Iran near its border with Iraq, damaging buildings and sending fearful residents running into the streets.
Morteza Salimi of Iran's Red Crescent told Iranian state television that 171 people were injured, most of them slightly. Kermanshah provincial Governor Houshang Bazvand similarly said there were injuries, but few people hospitalised.
Sunday night's earthquake struck near Sarpol-e Zahab in Iran's Kermanshah province, which suffered half of the casualties from last year's quake and where some still remain homeless.
