A massive protest broke out today during a memorial service for a young Iranian woman named Neda Agha-Soltan, who became the symbol of opposition.
The 27-year-old was shot dead as she watched protests from the sidelines, June 20. Shia Muslims mark 40 days after a death in a ceremony called the Arbayeen. Those leaders will also attend ceremonies to honour others killed in the violence.

When they arrived -- they were greeted by Iranian police...who used tear gas and batons break up the service.
Police also blocked opposition leader Mir Hossein Mousavi from attending the memorial.
Meanwhile, Iran has ordered the release of 140 people who were arrested during the protests that followed the June 12 election between Iran President Mahmoud Ahmadinejad and candidate Hossein Mousavi.
But 200 will remain in prison, and some will be put on trial beginning this weekend. There is growing concern about how those prisoners are being treated.
Thousands were involved in the protests, and at least 2,500 were sent to prison. Human rights organizations said those who remained in prison have faced torture -- and even death.
Public outrage and pressure from religious clerics have led Iran's supreme leader Ayatollah Ali Khamenei to close one of the most notorious prisons.
The order of the release of the people comes 40 days after Neda's death.
