Tehran — Iranian state TV has reported that 200 people were killed and 1 686 injured in the earthquake along Iran-Iraq border.
Monday's report said that rescuers are trying to help those affected.
The magnitude 7.3 quake was centered 19 miles (31 kilometres) outside the eastern Iraqi city of Halabja, according to the most recent measurements from the U.S. Geological Survey. It struck at a depth of 23.2 kilometres (14.4 miles), a shallow depth that can have broader damage.
The quake was felt as far west as the Mediterranean coast. Its worst damage appeared to be in Iran's western Kermanshah province, which sits in the Zagros Mountains that divide Iran and Iraq. Residents in the rural area rely mainly on farming to make a living.
Iraq's prime minister is seeking to reassure Iraqi civilians of their safety following an earthquake the previous night on Iraq's northeastern border with Iran.

Haider al-Abadi said he was following the matter and issuing a directive for the country's civil defense teams and "related institutions" to respond to the natural disaster. That's according to a statement released by his office late Sunday night.
The quake was felt across Iraq, shaking buildings and homes from Irbil to Baghdad and as far west as Anbar province.
Al-Abadi adds in his written statement: "God save Iraq and the Iraqi people."
Iran sits on many major fault lines and is prone to quakes. In 2003, a magnitude 6.6 earthquake flattened the historic city of Bam, killing 26,000 people.
