Al Jazeera Reports:

Juan Cole summarizes:

The political opposition in Iran held commemorations in Tehran, Isfahan, Shiraz, Ahvaz and Rasht for the deaths of protesters at the hands of security forces on June 20, especially for Neda Agha-Soltan, a young woman whose last moments on videotape became a heartbreaking sensation throughout the world. In Shiite Islam, mourning sessions are conducted for the deceased after 40 days as well as at other times. The technique of building larger and larger crowds locally helps the movement expand and avoid losing momentum.

Reports say that hundreds (some even say thousands) showed up at Tehran’s main seminary to mourn Neda and the others. Mir Hossein Mousavi and his wife Zahra Rahnavard attempted to visit the grave, but were turned away by security forces.

Hundreds also gathered at the Musalla Mosque in downtown Tehran, but were dispersed by security forces with tear gas and life ammunition. Clashes continued into the night.
