Iranian protesters, clad in black for mourning, filled Tehran's streets in a post-election rally Thursday that began and ended peacefully, witnesses said.
Tens of thousands of protesters wore black in remembrance of those who died in the violence that followed Friday's elections in which President Mahmoud Ahmadinejad was declared the landslide winner over his nearest challenger, Mir Hossein Mousavi.
Mousavi addressed the throng during the "ceremony of mourning," messages posted on Twitter indicated. The Iranian government banned foreign media from live coverage of "unauthorized" demonstrations, so accounts are based on Internet postings by witnesses or participants.
