Twin earthquakes rattled the Islamic Republic on Saturday. Iran state TV is reporting at least 180 dead and 1,300 people injured. The first of the two quakes measured 6.4 on the Richter scale and struck at just before 5 p.m. local time in Iran. The second followed soon after with a magnitude of 6.3. Earthquakes are a particular danger in Iran, where 50,000 people were killed in a single quake that struck in 1990. Rescue teams have been dispatched to the cities of Tabriz and Ahar.
