Iran has new problems. People are angry. The country's money, the rial, is very low. It is the lowest ever. This makes things very expensive. People are unhappy. They are protesting. This is like old protests.
Protests started last week. They are because of the bad economy. The rial is worth very little now. It takes many rials for one US dollar. This shows money problems. Many Iranians cannot buy food. This problem is for everyone. Many people blame the government. They also blame the leader.
The government will stop protests. Security forces will help. Iran's money problems are big. Sanctions make it worse. Bad management also causes problems.
