It's difficult to get a clear picture of what is happenign in Iran since protests in the financial district took place on October 3, 2010.

A second recommendation is  a report from Der Speigal originally that Iran mulls plans for a deliberate Gulf Oil spill which would have the West suspend sanctions to clean up the environmental disaster.
