BEIRUT AND TEHRAN — Rival camps within Iran's corridors of power intensified their threats against each other Friday, signaling potentially dangerous clashes within elite circles and the security establishment after the disputed June 12 reelection of President Mahmoud Ahmadinejad.
Hard-line clerics close to Ahmadinejad called for prominent reformist Mehdi Karroubi, a former speaker of parliament and a presidential candidate, to stand trial for making allegations of jailhouse rape and torture in the country's detention centers.
On the opposing side, a group of former reformist lawmakers issued a letter late Thursday demanding that Iran's supreme leader, Ayatollah Ali Khamenei, be investigated by the Assembly of Experts, clerics who have the power to replace the supreme leader, in relation to the election's violent aftermath.
The factional disputes, which are expected to get worse before the naming of the next Cabinet, come as street protests have faded.
"The ball of crisis is still rolling, if not on the streets, within the ruling establishment," said Mashallah Shamsolvaezin, a reformist journalist and human rights activist in Tehran.
Protesters, nursing bruises and stifled by late-summer temperatures, are sitting back for the moment, apparently hoping they can accomplish their minimal goal -- removing from power Ahmadinejad and his circle of hard-liners in the security apparatus -- without more bloodshed.
Analysts said that opposition figure Mir-Hossein Mousavi, Ahmadinejad's leading challenger in the election, has been reluctant to call for protests for fear he would be arrested. His news website, Ghalamnews.ir, has been shut down for days, and many of his deputies remain in prison.
"There is a plan for paralyzing the system and bringing down Ahmadinejad," said Mohsen Sazegara, a Washington-based analyst and political activist who supports the opposition. "But Mousavi can't announce it because he'll be arrested. If he doesn't say anything, it doesn't mean that within the opposition there's no plan."
For now, neither hard-liners nor reformists appear to be backing down.
At Friday prayers, Ayatollah Ahmad Khatami, a staunch supporter of Ahmadinejad, reiterated demands by his conservative allies that the judiciary put Karroubi on trial for making allegedly false accusations that prisoners swept up in a wave of protests were raped and tortured in prison.
