Another earthquake strikes northern Iran

One person has died of a heart attack and at least 75 people were injured after a 4.2 magnitude earthquake struck 50km west of Tehran, state media reported. 

The earthquake, which struck at 12.54am local time, was an aftershock of a bigger 5.2 magnitude quake on 20 December, which left two people dead.

Most of the injured were trying to escape buildings and were released from hospital after treatment, Iran's Emergency Medical Services said.

Tremors were also felt in the capital this morning, the Independent reported.

The earthquake comes six weeks after a 7.2 magnitude earthquake hit the country and became the deadliest of 2017, killing more than 620 people.
