As Iran's opposition gears up for demonstrations in Tehran Tuesday, the government is allegedly working to undercut the movement. According to websites allied with Mir Hossein Mousavi and Mehdi Karroubi, the two opposition leaders have been arrested.  

For weeks, the leaders have been under house arrest but reports from the opposition website Kaleme say they've been "transferred to Heshmatiyeh jail in Tehran."

As the AP's Ali Akbar Dareini writes:

The development is a sharp escalation following warnings by an international human rights group, which said Sunday the two leaders and their wives were in grave danger after security forces apparently took them from their homes, where they had been under house arrest...

Prominent pro-reform cleric, Grand Ayatollah Youssef Saanei, denounced the government's treatment of the two opposition leaders.

"We are witnessing anti-Islamic and anti-human attacks against political opponents," said Saanei in a statement posted on a reformist website, kaleme.com.
