Politkovskaya death retrial opens

Sergei Khadzhikurbanov and brothers Dzhabrail and Ibragim Makhmudov were acquitted in February of involvement in Ms Politkovskaya's death.

But critics said the trial was farcical and Russia's Supreme Court ordered a retrial over procedural violations.

Ms Politkovskaya was a staunch critic of the Kremlin - her supporters allege official involvement in her death.

The Kremlin has dismissed such claims.
