Woman 'didn't see killer of Russian opposition leader Nemtsov'

A 23-year-old Ukrainian model who was with slain Russian opposition leader Boris Nemtsov when he was shot dead has said she did not see the gunman who pulled the trigger.

The emotional account by Anna Duritskaya in a TV interview came amid speculation about who was responsible for the high-profile assassination near the Kremlin in Moscow and what it means for Russia.
