Since mid-November, Iranian citizens have filled the streets in scores of cities in all 31 of the nation's provinces to denounce the mullahs and the Rouhani government.

The Iranian regime is lashing out against the demonstrators with far more ferocity than in previous protests, but the repression seems to be making more people mad and the protests just keep growing.

"There's nothing that can stop it, no matter how mush pressure the regime exerts," said Alireza Jafarzadeh, deputy director of the National Council of Resistance of Iran office in Washington.

He explained why the Iranian government is acting far more viciously towards its own people in this round of protests.

"You're talking about a regime that is paranoid. It's weak. It's vulnerable, and people now feel that they have the momentum on their side," said Jafarzadeh.
