The United States “honors the legacy” of Russia’s campaigning journalist Anna Politkovskaya, murdered in 2006, and urges Moscow to prosecute all guilty of killing her, a spokeswoman for the U.S. Department of State said. “October 7 marks the fifth-year anniversary of the murder of Russian journalist Anna Politkovskaya. Her reporting on the war in the North Caucasus brought to light the violation of human rights and the suffering of the victims in this conflict. We honor Anna’s legacy as a courageous journalist,” Victoria Nuland said in a statement. “While we welcome the recent arrest of suspects in her murder, justice will not be done until all those involved in the crime are identified and prosecuted,” she added. Politkovskaya, well-known for her investigative journalism into human rights violations in the Russian North Caucasus republic of Chechnya, was shot dead in her apartment block in Moscow on October 7, 2006. Investigators say she was killed because of her journalistic activities. Politkovskaya worked for Novaya Gazeta. Politkovskaya\'s suspected killer Rustam Makhmudov was detained in Chechnya in May 2011. In late August, police also detained former police colonel Dmitry Pavlyuchenkov on charges of organizing the murder.
