TEHRAN – An Iranian court has ruled to imprison the son of Mehdi Karroubi for having published an open letter written by his father.

Mohammad Hossein Karroubi will be jailed for 6 months on charge of attempt to undermine national security, ILNA reported on Monday.

In the letter, Karroubi had urged President Rouhani to ask the Supreme Leader to agree to a court hearing about his case.

Mehdi Karroubi, who claimed vote rigging in the 2009 presidential election, is under house arrest.
