TEHRAN, Iran (AP) — Iran has raised the death toll from Saturday’s twin earthquakes to 306, a day after rescuers called off the search for survivors.

Heath Minister Marzieh Vahid Dastjerdi told a session of parliament Monday that the number jumped by about 50 after victims expired in the hospital. More than 3,000 people were injured in the earthquakes.

Scores of aftershocks have coursed through Iran’s mountainous northeast since the 6.4 and 6.3 magnitude quakes hit the region, where some 300,000 people live near the borders with Azerbaijan and Armenia.

Iran is located on seismic fault lines and is prone to earthquakes. In 2003, some 26,000 people were killed by a 6.6 magnitude quake that flattened the historic southeastern city of Bam.
