Hundreds of anti-riot police have surrounded Behesht Zahra Memorial Park in Tehran today to prevent a visit by opposition leaders Mir Hossein Mousavi, Mehdi Karrubi and their supporters to the graves of protesters slain in post-election demonstrations in Iran.
The memorial service was to start at 4:00 pm Tehran time. Reports from Tehran indicate that the police are trying to disperse mourners who have begun to arrive at the cemetery and are arresting a number of them. Thousands are expected to attend.
Today is the 40th Day anniversary of the death of Neda Soltan and a number of other protesters. Neda's mother is also expected to attend the memorial service today. 40th Day anniversaries are important mourning occasions in Shia religion.
