Second Day of Renewed Clashes Between Opposition Movement and Iranian Government

Iranian Nobel Peace Prize winner Shirin Ebadi says her sister has been arrested by the intelligence services, hours after opposition figures were detained.

Ms Ebadi said her sister Nooshin, a medical professor, was arrested at home on Monday evening, and taken to prison.

On Monday, Iranian authorities arrested several prominent aides of opposition leaders and a former foreign minister, according to opposition Web sites — the latest move by Tehran in its more than six-month effort to stamp out anti-regime protests. The arrests followed a sometimes-bloody crackdown on protests that started last week and on Sunday erupted into violence in which at least eight people died.
