Three days of protests broke out on Sunday in Tehran’s Grand Bazaar, with hundreds of angry shopkeepers denouncing a sharp fall in the value of the Iranian currency.

The disturbances are a major challenge, but analysts expect the leadership will survive despite factional infighting and growing economic problems.

However, the weekend protests quickly acquired a political edge, with people shouting slogans against Iran’s ultimate authority, Supreme leader Ayatollah Ali Khamenei, and other top officials, calling them thieves who should step down.

Bazaar merchants, mostly loyal to the leadership since the 1979 Islamic Revolution, are angry at what they see as the government’s muddled response to the crisis, which they said had sent prices soaring and made trading almost impossible.
