Russian prosecutors announced on Monday the arrest of 10 suspects in the death of Anna Politkovskaya, a Russian investigative journalist who was shot and killed Oct. 7, 2006. Politkovskaya was a critic of Russian President Vladimir Putin, and there was speculation that it was Putin (or a close supporter) who ordered her killing. Russian authorities said Monday that she had been killed by an organized crime group — one headed by a Chechen, but also containing law enforcement officers, including one member of the Federal Security Service (FSB), Russia's intelligence organization. Prosecutors said she had been writing about abuses by security forces in Chechnya and this triggered the killing. Most importantly, the chief prosecutor said the killing was linked to Kremlin opponents living abroad.
