Iran protests: 'Iron fist' threatened if unrest continues

Iran's Revolutionary Guards have warned anti-government protesters they will face the nation's "iron fist" if political unrest continues.

Three days of demonstrations over falling living standards have become the biggest show of dissent since huge pro-reform rallies in 2009.

A Revolutionary Guards commander said the protests had degenerated into people chanting political slogans and burning public property.

Two protesters died of gunshot wounds.

The authorities in Dorud in western Iran said security forces did not open fire on demonstrators, and blamed the deaths instead on Sunni Muslim extremists and foreign powers
