Iran's increasingly isolated opposition leader has effectively ended his role in street protests, saying he'll seek permits for future rallies.
Meanwhile, a leading cleric demanded in a nationally broadcast sermon Friday that leaders of the unrest be punished harshly and said some are "worthy of execution."
Iran's ruling clergy has widened its clampdown on the opposition since a bitterly disputed June 12 presidential election, and scattered protests have replaced the initial mass rallies.
The official Web site of opposition leader Mir Hossein Mousavi, his main tool of communicating with his supporters, was hacked Friday, leaving it blank, an aide said.
On Thursday, Mousavi said for the first time that he was being isolated by authorities and pressured to drop his presidential election challenge.
