'How Do I Celebrate The New Year Without You, Neda?'

This video shows the mother of Neda Agha Soltan crying at her daughter's grave on March 18.

"How do I celebrate the new year without you, dear Neda?” she asks.

Neda is the young woman whose graphic death, captured on video, became an icon of the Green opposition movement.

A shadow has been cast on the Iranian new year -- marked on March 21 -- by the continuing postelection crisis in the country.
