Mohammad Javad Zarif said the political battles had become so tense that it brought on back pain and spasms. He said on his Facebook page that he cancelled appointments and went to hospital for a check-up late yesterday.
The source of his distress: An article in a hard-line newspaper that Zarif said misquoted him on the subject of the new Iranian administration's outreach to the US.
In another sign of the Rouhani camp's moves to steer a more moderate course, government spokesman Mohammad Bagher Nobakht was quoted today by the semiofficial Fars news agency saying authorities are considering freeing two opposition leaders who have been under house arrest since early 2011.
The two figures, Mir Hossein Mousavi and Mahdi Karroubi, ran in 2009 presidential elections, challenging Rouhani's predecessor, Mahmoud Ahmedinejad. They then led giant protests over Ahmadinejad's disputed win in that election. Since last month, officials have freed more than 90 people jailed in the crackdowns on those protests.
Iranian hard-liners, including commanders in the powerful Revolutionary Guard, have said Rouhani went too far in reaching out to Washington. The Guard chief commander, Gen. Mohammad Ali Jafari, had praised Rouhani but called the phone call a "tactical mistake.
