Tehran: A 5.7-magnitude earthquake struck southwest Iran near the border with Iraq on Monday, causing one death due to a heart attack and dozens of injuries, the country’s relief and rescue organisation said. The quake, whose epicentre was in the Masjed Soleiman area of Khuzestan province, hit at 11:30 am (0700 GMT) at a depth of 17 kilometres, the national seismological centre reported. The region was rattled by seven aftershocks, the strongest of which measured 4.7 magnitude, it said.

In nearby cities and villages affected by the quake, there were “only minor cracks in buildings” and roads to some villages were cut off. Iran sits on top of major tectonic plates and sees frequent seismic activity. In November 2017 a 7.3-magnitude tremor in the western province of Kermanshah killed 620 people. In 2003, a 6.6-magnitude quake in southeast Iran decimated the ancient mud-brick city of Bam and killed at least 31,000 people. Iran’s deadliest quake was a 7.4-magnitude tremor in 1990 that killed 40,000 people in northern Iran, injured 300,000 and left half a million homeless.
