There have been so many villages in marginal provinces and near the Iranian border with Pakistan, Afghanistan and Iraq that have been evacuated for different reasons. One is water, which I'm mostly concerned about, but also, they are mostly from the Sunni minority as well. Therefore, it's ethnic and also religious over there.
Those minorities have been deprived of their rights and the government has not helped them or has created a situation where they had no options but to leave. That is what I have studied in the last few years.
