Exiled crown prince urges world to help protesters topple Iran's government

The exiled son of the last Iranian shah (king) has called on the world to help protesters topple Iran's government, saying he is confident "the Islamic Republic will fall - not if, but when".

Reza Pahlavi, an opposition leader based in the US, called for "surgical" strikes on Iran's Revolutionary Guards which he said "will facilitate our task and prevent more loss of life".

More than 2,000 protesters have been killed, according to human rights groups, in demonstrations that started over the economy on 28 December and turned into calls for the end of the rule of Iran's Supreme Leader Ali Hosseini Khamenei.

The Iranian government has called the protests "riots" backed by Iran's enemies.

Pahlavi has emerged as a prominent figure in Iran's fragmented opposition and has previously urged Iranians to escalate their protests.

However protesters have been met with deadly force by authorities, masked by a near total shutdown of the internet and communication services.

Speaking at a news conference in Washington, Pahlavi vowed to return to Iran and laid out a plan for creating a new constitution in the country.

He claimed that sections of Iran's security apparatus had refused to take part in the crackdown and that the Iranian authorities had brought in fighters from foreign militias to quell the protests.

Asked about future leadership in Iran, Pahlavi said: "It's for the Iranian people to decide."

"I am trying to help them liberate themselves."

He said he supported a governing programme based on the principles of Iran's territorial integrity, a separation of religion and state, individual liberties and the right of the Iranian people to decide on the form of democratic government they want.

The current wave of protests began after shopkeepers in Tehran went on strike over the rising cost of living and the depreciating value of the currency.

They quickly spread across the country and turned against Iran's clerical establishment, particularly the Supreme Leader, Ayatollah Ali Khamenei. The slogans chanted by demonstrators have included "Death to the dictator" and "Seyyed Ali [Khamenei] will be toppled this year".

According to the US-based Human Rights Activists News Agency (HRANA), at least 2,453 protesters have been killed since the unrest began, as well as 14 children, 156 people affiliated with the security forces or government, and 14 uninvolved civilians.

It reports that another 18,470 protesters have been arrested.
