Mousavi's attendance is noted on his Facebook page, and there is speculation that former President Mohammad Khatami also will attend the rally, scheduled for 4 p.m. (7:30 a.m. EDT) in Tehran's Baharestan Square, outside of the Iranian parliament.
Also on Mousavi's Facebook page, online supporters have posted that peaceful protests will be held at the same time in over 15 countries and 10 American cities.
Many in Tehran seem hesitant to confront the feared Revolutionary Guard and members of the Basij militia, suggesting the harsh response wrought by hard-line President Mahmoud Ahmadinejad and supreme leader Ayatollah Ali Khamenei to large and boisterous demonstrations may have weakened the opposition's resolve.
