Turkey, three of the dead were children, and 50 people were injured, including nine critically, the health ministry said.
The shallow tremor caused more than 1,000 buildings to collapse in Turkey, prompting a brief rescue effort to find those trapped under rubble.
The quake damaged buildings some 90 km (56 miles) to the west in the Turkish city of Van, and to the east in dozens of villages in Iran, where state TV said 75 people were injured including six in hospital.
