AP: "Police used tear gas and batons Tuesday to disperse resurgent anti-government protesters demanding the release of opposition leaders in the biggest clashes in Iran's capital since demonstrators stormed back to the streets two weeks ago, witnesses and opposition websites said.
The recent return of skirmishes in the heart of Tehran — absent for more than a year after relentless crackdowns — borrow some raw inspiration from uprisings in the neighboring Arab world. But it also reflects a possible miscalculation by authorities who sought to silence opposition leaders but instead gave their supporters a new rallying point.
Reports by family members and opposition websites claim the two most prominent anti-government figures, Mir Hossein Mousavi and Mahdi Karroubi, have been moved from house arrest to full-time detention along with their wives. Iranian authorities deny the reports, but the two opposition leaders have not been seen in public or posted statements on their websites in more than a week."
