A Moscow court opened a new trial Wednesday for three suspects in the murder of investigative journalist and Kremlin critic Anna Politkovskaya, but then quickly adjourned proceedings until Friday.

Lawyers for the slain journalist's family called for an entirely new investigation into the murder, and termed the previous probe incomplete.  

In June, Russia's Supreme Court overturned a February jury verdict acquitting the three - Chechen brothers Dzhabrail and Ibragim Makhmudov and former security police officer Sergei Khadzhikurbanov - of helping organize the murder. The jury had cited insufficient evidence as grounds for the decision.

Politkovskaya researched and wrote extensively about rights abuses in Chechnya. She was gunned down in her Moscow apartment building in October 2006.   

Colleagues say Politkovskaya's reporting on atrocities in Chechnya angered the Kremlin, while earning her international acclaim.
Last month's killing of a colleague, Natalya Estemirova, places the Politkovskaya case under renewed scrutiny.  Authorities found the body of the acclaimed rights campaigner, who worked alongside Politkovskaya, just hours after she was abducted. She was shot in the head and chest.
