Rights activists and supporters are commemorating the death of Russian investigative journalist Anna Politkovskaya, the seventh anniversary of her murder.

Russia's "Novaya gazeta" newspaper, where Politkovskaya worked, unveiled a commemorative plaque to the journalist. Commemorative gatherings and pickets were also organized at other locations in Moscow and in St. Petersburg.

In Berlin, a concert was staged to show solidarity with victims of violence and rights violations in Russia.

Politkovskaya, who reported on atrocities committed by Russian forces and pro-Kremlin armed groups in Chechnya, was shot dead outside her Moscow apartment on October 7, 2006. Five suspects are on trial for alleged involvement in her murder.
