Background: Anna Stepanovna Politkovskaya (Russian: Anna Stepanovna Politkovskaia, IPA: ['an:@ sjtjI'pan@vn@ p@ljIt'kofsk@j@]; Ukrainian: Ganna Stepanivna Politkovs'ka ['han:a ste'panjiuna poljit'kousjka]; nee Mazepa [ma'zepa]; 30 August 1958 - 7 October 2006) was a Russian journalist, writer, and human rights activist who reported on political events in Russia, in particular, the Second Chechen War (1999-2005).
Context: Politkovskaya won a number of awards for her work. She used each of these occasions to urge greater concern and responsibility by Western governments that, after the 11 September attacks on the United States, welcomed Putin's contribution to their "War on Terror". She talked to officials, the military and the police and also frequently visited hospitals and refugee camps in Chechnya and in neighbouring Ingushetia to interview those injured and uprooted by the renewed fighting.  In numerous articles critical of the war in Chechnya and the pro-Russian regime there, Politkovskaya described alleged abuses committed by Russian military forces, Chechen rebels, and the Russian-backed administration led by Akhmad Kadyrov and his son Ramzan Kadyrov. She also chronicled human rights abuses and policy failures elsewhere in the North Caucasus. In one characteristic instance in 1999, she not only wrote about the plight of an ethnically-mixed old peoples' home under bombardment in Grozny, but helped to secure the safe evacuation of its elderly inhabitants with the aid of her newspaper and public support. Her articles, many of which form the basis of A Dirty War (2001) and A Small Corner of Hell (2003), depict a conflict that brutalised both Chechen fighters and conscript soldiers in the federal army, and created hell for the civilians caught between them.  As Politkovskaya reported, the order supposedly restored under the Kadyrovs became a regime of endemic torture, abduction, and murder, by either the new Chechen authorities or the various federal forces based in Chechnya. One of her last investigations was into the alleged mass poisoning of Chechen schoolchildren by a strong and unknown chemical substance which incapacitated them for many months.
