18 year old Zeinab cries near her parents' grave after an earthquake hit a village near the city of Varzaqan in northwestern Iran on Saturday 11 August. Twin earthquakes in Iran have killed at least 306 people and injured more than 2,000, Iranian state television said on Monday, a day after the search for survivors was called off by rescuers. Thousands spent the night outdoors after their villages were leveled and homes damaged in the country's northwest. Iran is located on seismic fault lines and is prone to earthquakes. It experiences at least one earthquake every day on average, although the vast majority are so small they go unnoticed.
