Tehran - A powerful earthquake shook the Iran-Iraq border late on November 12, killing 207 people and injuring 1 686 in the mountainous region of Iran alone, Iranian state media said.The Baghdad government did not immediately give word on casualties in that country, though Prime Minister Haider al-Abadi issued a directive for the country's civil defence teams and "related institutions" to respond to the natural disaster.The magnitude 7.3 quake was centred 31km outside the eastern Iraqi city of Halabja, according to the most recent measurements from the US Geological Survey. It struck at a depth of 23.2km, a shallow depth that can have broader damage. Magnitude 7 earthquakes on their own are capable of widespread, heavy 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.Iranian social media and news agencies showed images and videos of people fleeing their homes into the night. Some 50 aftershocks followed.Iran's state-run television reported the increase in casualties early on November 13 and said rescue work was continuing overnight and would accelerate during the daytime.Iran's Supreme Leader Ayatollah Ali Khamenei offered his condolences on the morning of November 13 and urged rescuers and all government agencies to do all they could to help those affected, state media reported.The semi-official ILNA news agency said at least 14 provinces in Iran had been affected by the earthquake.Officials announced that schools in Kermanshah and Ilam provinces would be closed on November 13 because of the temblor.Iranian state TV also said Iraqi officials reported that at least six people dead inside Iraq, along with more than 50 people injured in Sulaymaniyah province and about 150 in the town of Khanaquin.Iran sits on many major fault lines and is prone to near-daily quakes. In 2003, a magnitude 6.6 earthquake flattened the historic city of Bam, killing 26 000 people. The last major casualty earthquake in Iran struck in East Azerbaijan province in August 2012, killing over 300 people.
