Chechnya Policeman 'Confesses' Involvement in Nemtsov Murder

A Russian court on Sunday charged two men with the murder of opposition activist Boris Nemtsov, including an ex-police officer from Chechnya who confessed to his involvement in what investigators said was a contract killing.

Four other suspects have denied connection to the February 27 killing of Nemtsov who was shot four times in the back while walking with his girlfriend late at night along a bridge outside the Kremlin, in the most high-profile assassination of President Vladimir Putin's rule that has sent shivers through the opposition.

Interfax news agency quoted a law enforcement source as saying that a sixth suspect threw a grenade at police who came to arrest him in the Chechen capital and killed himself with another grenade Saturday.

In Moscow, masked, heavily armed police marched the five handcuffed suspects through hallways packed with journalists and into two separate courtrooms where they were placed inside defendants' cages and ordered to be held for around two months pending the investigation.

According to documents read out in court, the accused are charged under a section of the Russian criminal code which shows investigators believe the murder was carried out by a group of people for financial gain, the Interfax news agency reported.

The charges also involve extortion and banditry. Investigators said they were still seeking others who may have been involved.

However, as in a string of other killings of Russian opposition figures, officials have yet to shed light on who might have ordered Nemtsov's murder.

Zaur Dadayev, a former deputy commander in the Chechen police, and Anzor Gubashev, who worked for a private security company in Moscow, were arrested on Saturday in the province of Ingushetia, which neighbors Chechnya.

They were both charged with murder but Gubashev denied involvement.

"The participation of Dadayev is confirmed by his confession," said presiding judge Nataliya Mushnikova, according to state news agencies.

Court spokeswoman Anna Fadeyeva told the RIA Novosti news agency that the other three men were only considered suspects at this stage. 

They are Gubashev's younger brother Shagid, Ramzat Bakhayev and Tamerlan Eskerkhanov, who news agencies reported had also been arrested in Ingushetia.

The men are all from the volatile northern Caucasus region where Russia has fought two devastating wars against Chechen rebels and where security forces continue to clash with Islamist insurgents.

"The suspects denied their involvement in this crime but investigators have proof of their involvement," a representative for the probe told the court.

However no information emerged as to the possible motive the men could have had in killing the former prime minister turned charismatic opposition leader who was one of the last outspoken opponents to Putin.

Nemtsov's allies believe his assassination was a hit ordered by the top levels of government determined to silence dissenters. The allegation has been strenuously denied.

- Russia 'crossed the line' -

The murder in one of the most heavily policed parts of the Russian capital sent shockwaves through an opposition which has seen several critics of the Kremlin killed in recent years and which accuses Putin of steadily suppressing independent media and opposition parties.

Nemtsov's daughter Zhanna Nemtsova, in an interview with CNN from Germany, said the murder was obviously "politically motivated."

"I think that now, Russia has crossed the line after this murder, and people will be frightened to express their ideas which contradict ... the official standpoint."

Her comments echo those heard from Kremlin critics since the killing such as activist Alexei Navalny, who accused "the country's political leadership" of ordering a hit on Nemtsov.

Nemtsov, who had long complained of being followed and having his phone tapped, had spoken of his fear of being killed.

Putin has described Nemtsov's killing as a tragedy that brought disgrace on Russia and vowed that everything would be done to bring to justice those who committed a "vile and cynical murder."

- Fifth column -

Many Russians say that failing direct involvement, Putin is still to blame for whipping up hatred against the opposition by regularly referring to them as a "fifth column" of traitors and spies -- a message spread daily by all-powerful state media.

He first used the term fifth columnist -- which originated during the Spanish civil war and refers to a group of people undermining a nation from within -- after he ordered the annexation of Crimea in Ukraine last year, plunging relations with the West to lows not seen since the Cold War.

Investigators have suggested Nemtsov's killers wanted to destabilize Russia while Kremlin-loyal politicians have referred to a Western plot.

Investigators say they are also probing the possibility he was assassinated for criticizing Russia's role in the Ukraine conflict or for his condemnation of January's killings at the Charlie Hebdo satirical weekly in Paris by Islamist gunmen.

At the time of his death, Nemtsov was believed to be working on a study documenting the secret deployment of Russian troops in Ukraine, something the Kremlin denies doing.
