At least 335 people have been killed after a 7.3-magnitute earthquake hit the border region between Iraq and Iran on Sunday.

Roughly 2,500 people have been injured and the death toll is expected to rise when search and rescue areas reach the more remote areas.

The majority of those killed were in Iran’s western Kermanshah province, with state media reporting 100 dead in the town of Sarpol-e Zahab alone.

While more deaths have been confirmed in Iran, the earthquake’s epicentre was across the border in Iraq, about 350km from Baghdad, where people ran out on onto the streets in panic and the mosques broadcasted prayers throughout the night.

Tremors were felt throughout the country and as far away as the UAE, Kuwait and Lebanon, media agencies in those countries reported.

The death toll is expected to climb in both Iran and Iraq in the coming days. The Iranian Red Crescent said that 70,000 people were in need of emergency shelter.
