Tyrants and dictators are frequently more sensitive about bad publicity than you might expect. International campaigns to save individuals from torture and execution sometimes end happily, although some regimes – China, Burma and Iran come to mind – are more intransigent than most. For two months now, the international community has been trying to save Sakineh Mohammadi Ashtiani, the Iranian woman sentenced to death by stoning, with little evidence thus far of any second thoughts on the part of the Iranian authorities.

Last week the French foreign minister, Bernard Kouchner, offered to fly to Tehran to plead for Ashtiani’s release, adding his name to an impressive list of politicians, human rights campaigners and celebrities who have rallied to her cause. According to president Mahmoud Ahmadinejad, Iranian women are “the freest in the world”, a claim that speaks volumes about the nature of his regime.
Obviously international pressure must be kept up, but this thoroughly justified outrage has not so far spared Ashtiani from further punishment. The most recent reports from Tabriz, where she has been in prison for four years, are alarming: she has been flogged for a second time, according to her son and her lawyer, and still faces execution by stoning.

Ashtiani has not been allowed visits for almost a month, and her supporters discovered from former cellmates that she had been sentenced to 99 lashes for “spreading corruption and prostitution” after The Times newspaper in England published an unveiled photograph of a woman it mistakenly believed to be her. Even more worrying is the fact that she was given confirmation of her death sentence on 28 August, and was told that it would be carried out the following day. It wasn’t – such terror tactics are characteristic of the regime – but her supporters fear that she might be killed after Ramadan ends on Friday.

In 2008, Iran’s judiciary announced a moratorium on executions by stoning, following an outcry about such barbaric sentences, but that did not prevent two men being stoned to death on 26 December that year. The International Committee Against Stoning believes that the real figures are much higher: they say that 109 people have been stoned to death in Iran and 25 are awaiting execution by lapidation. What is known for certain is that Iran had the highest per-capita execution rate in the world in recent years, with at least 320 people executed in 2008 alone, including a mass hanging of 29 victims. As well as a variety of criminal offences, adultery – one of the “charges” against Ashtiani – and same-sex relations carry the death penalty.

Last month, she was forced to go on a state-run television programme and “confess” to adultery and involvement in her husband’s murder; her lawyer said she was tortured for two days before the interview was recorded in Tabriz prison. Such “confessions” are not unusual in Iran, which uses accusations of “illicit” sexual relationships to discredit people the regime doesn’t like.

Nor are threats of imminent execution unusual, according to former political prisoners I’ve interviewed; an Iranian editor told me he lived in fear for a whole year after being sentenced to death in Tehran’s notorious Evin prison. He also said his spirits lifted each time he heard about foreign demonstrations in his support, even though they led to savage beatings. He was eventually taken to Tehran airport and hustled on to a plane to Germany, where he needed medical treatment for a broken jaw. Of course Ashtiani isn’t a political activist; she’s a woman who happens to have fallen foul of the harsh and unjust punishments handed down by a theocratic regime. Her case has at least received international attention, unlike many of the protesters who were rounded up following last year’s hotly disputed presidential election. Some emerged from prison weeks or months later with horrific stories of torture and repeated rape, but many were too traumatised to speak out about what had happened to them.

Weirdly, Ahmadinejad’s regime continues to have apologists. They claim that Iran is a democracy, ignoring the fact that an unelected council of guardians has the power to veto all legislation and disqualify election candidates from reformist parties; in 2005, more than a thousand candidates were barred from standing. They encourage Ahmadinejad to stand up to “bullying” over Iran’s nuclear programme, unconcerned by the prospect of this rogue regime obtaining nuclear weapons.

There’s reason to think Iran’s nuclear programme is so important to the regime precisely because it has so little else to boast about. The economy is in poor shape – inflation reached 30% in 2009 – and last year’s demonstrations exposed the profound unpopularity of the clerical regime. Young Iranians are desperate to emigrate to Western countries they’ve supposedly been taught to hate, and no one knows when unrest will flare up again.

Ahmadinejad’s regime isn’t going to collapse in the immediate future. But it fears its days are numbered. What kind of regime flogs a 43-year-old woman and threatens to stone her to death? The appalling treatment of Sakineh Mohammadi Ashtiani is a testament to the regime’s weakness, not its strength.
