Iran-Iraq border earthquake live updates: Iran's emergency services chief Pir Hossein Koolivand said it was 'difficult to send rescue teams to the villages because the roads have been cut off... there have been landslides'

(That's why they have Helicopters)

A 7.3 magnitude earthquake rocked the mountainous Iran-Iraq border, killing over 300 people, injuring hundreds more and triggering landslides that were hindering the rescue effort, officials said.

Footage posted on Twitter showed people fleeing a building in Sulaimaniyah, northern Iraq, as windows shattered at the moment the quake struck late on Sunday, while images from the nearby town of Darbandikhan showed major walls and concrete structures had collapsed.

“We are in the process of setting up three emergency relief camps,” said Mojtaba Nikkerdar, the deputy governor of Iran’s Kermanshah province.

The quake hit 30 km southwest of Halabja in Iraq’s Kurdistan at around 9.20 pm, when many people would have been at home, the US Geological Survey said. Iran’s emergency services chief Pir Hossein Koolivand said it was “difficult to send rescue teams to the villages because the roads have been cut off… there have been landslides”.
