August 28, 2007 (RFE/RL) -- Russian Prosecutor-General Yury Chaika says foreign-based enemies of the Kremlin were behind the October 2006 murder of reporter Anna Politkovskaya.

But the crusading journalist's colleagues have been conducting their own probe into the killing -- and accuse Chaika of playing politics instead of solving the crimes.

Sergei Sokolov, the deputy editor of "Novaya gazeta," where Politkovskaya worked, told RFE/RL that "the scenario that Mr. Chaika put forth is just a scenario which has no basis." He accused Russian authorities of politicizing the investigation into the journalist's murder.

"We have a different scenario that we are working on about who ordered this [murder]. We think we still need to investigate this more, and do so professionally. We don't want to turn this into a political event," Sokolov said.

Officers Implicated

Chaika announced on August 27 that 10 people had been arrested in connection with Politkovskaya's murder on October 7, 2006.

Among those accused of organizing and carrying out the killing are a Chechen crime boss, a Federal Security Service (FSB) officer, a police major, and three former police officers.

"Novaya gazeta" has been conducting its own investigation into the murder. Sokolov says the paper's findings supports Chaika's allegations -- to a degree.

"As far as those who have been detained are concerned, we believe that they most likely were involved in this crime," he said.

But there is an aspect of Chaika's theory that Sokolov says is not at all supported by the "Novaya gazeta" investigation -- the allegation that "foreign-based" forces were behind the killing.

Chaika claims the masterminds behind Politkovskaya's assassination were living outside of Russia, and that the murder was part of a plot to discredit President Vladimir Putin and destabilize the country in the run-up to national elections.

'Foreign Enemies'

Sokolov noted that Chaika's comments nearly exactly echoed a statement made by Putin shortly after Politkovskaya's death. At the time, Putin claimed that "people who are hiding from Russian law enforcement have been hatching plans to sacrifice someone and create an anti-Russian wave in the world."

The prosecutor-general didn't name names when referring to the Kremlin's alleged foreign enemies, but he appeared to be referring to one person: Boris Berezovsky, the former Kremlin insider turned fierce Putin critic who is living in exile in London.

Berezovsky called the apparent effort to link him to Politkovskaya's death "sick," adding that it was a "hysterical reaction" to his opposition to Putin.

Politkovskaya -- a frequent critic of Putin whose journalism chronicled the killings, kidnappings, and torture of civilians in Chechnya -- was gunned down in the stairwell of her Moscow apartment building on October 7, 2006.

Her reporting had angered the Kremlin and the Moscow-backed Chechen leadership.

In his interview with RFE/RL, Sokolov declined to say who -- according to the "Novaya gazeta" investigation -- was behind Politkovskaya's murder:

"Unlike lawyers such as Prosecutor-General Chaika and those in the FSB, we don't want to reveal secrets of the investigation and violate the presumption of innocence. This would only harm people's understanding" of the case, he said.
