Iranian opposition leader Mehdi Karroubi, under house arrest for the past six years, was hospitalized on August 17 after going on hunger strike to demand a trial.

:: Iranian opposition leader Mehdi Karroubi, under house arrest for six years, ended his hunger strike late Thursday after the government agreed to remove intelligence agents from his home.

However, his demand to face trial — he has never been charged since being placed under house arrest in 2011 — appears no closer to being granted.

Karroubi, 79, stopped eating and drinking on Wednesday morning and was hospitalized a day later with high blood pressure.

Mohammad Hossein, Karroubi’s son, told reformist website Jamaran that the opposition leader rhad met with Health Minister Ghazizadeh Hashemi on Thursday, and was secured promises that convinced him to end the hunger strike.

Saham news, a website linked to the Karroubi family, said the minister had promised to remove the agents from his home.

Karroubi and fellow reformist leader Mir Hossein Mousavi were candidates in Iran’s disputed 2009 presidential election which sparked months of mass protests over claims that the polls were rigged in favor of hardline incumbent Mahmoud Ahmadinejad.

Both were placed under house arrest in 2011 for their role in the protests, which were brutally put down by the regime.

Karroubi’s wife Fatemeh told Saham news earlier this week that his first demand was the removal of intelligence ministry agents and security cameras that had been recently installed inside their home, which she said “has no precedent before or after the (1979 Islamic) revolution in any house arrest”.

“Second… in case of continuation of the house arrest, they should arrange a public trial,” she said.

Karroubi “does not expect a fair trial” but wants it to be public and would respect the verdict, she added.

In March, Iran sentenced Karroubi’s eldest son Hossein to six months in prison for “propaganda against the regime” after he published a letter that his father had written to Iran’s current president, Hassan Rouhani, considered a political moderate, calling for a trial.

Karroubi’s failing health — he underwent a heart operation earlier this month — poses a potential problem for the Iranian regime, with fears that it could provide a lightning rod for renewed protests.

Rouhani won a resounding re-election victory in May, in part by rallying reformists and vowing to win the release of Mousavi and Karroubi.

But hardline judiciary chief Ayatollah Sadegh Larijani threw cold water over Rouhani’s promises shortly after the election.

“Who are you to end the house arrest?” Larijani said in May.
