A short video clip from RFE/RL has great footage from the Azerbaijan/Iran border, where thousands of Azeris now line up every day in order to get to the other side to buy basic food staples, which have become prohibitively expensive on their side of the border. You can watch it here.
With some suggesting that the recent wave of revolution and unrest in the Middle East and other regions is directly tied to the recent surge in the price of food, the scene at the Iranian border is likely making Azeri officials nervous. Which may help explain this.
