Anna Politkovskaya three years on

It's three years since Russian campaigning journalist Anna Politkovskaya was murdered. Her killers have yet to be brought to trial.

The general secretary of Reporters Without Borderswas refused a visa to travel to Russia - Jean-François Julliard had intended to take part in a news conference in Moscow to mark the third anniversary.

Amnesty has renewed its campaign to persuade the Russian authorities to take an interest in the case.

Twenty-two journalists have been killed in Russia since the start of the decade.
